4th sem (5) : Creating and enhancing Power Point Presentation

 Aim : Creating and enhancing Power Point Presentation

Apperatus : A computer system with latest power point presentation.

Digram:

Procedure : Algorithm

Here is a way you can enhance it with music, images, and videos.

1. Crop Pictures to Fit Shapes

To add even more visual flair, you can also crop an image to make it automatically fit inside your shape.

2. Play Music in the Background During a Presentation

punch up your PowerPoint presentation with some tunes. While playing music in the background certainly isn’t always appropriate, adding audio for the duration of your presentation is an easy process that can make your slides a bit more interesting.

3. Combine Shapes to Create a Custom Shape

in PowerPoint, the standard shapes in the program might not suit your needs. We’ll show you how to merge multiple shapes to create your own custom shapes.

4. Add Sound Effects to Animations

The more interesting your PowerPoint slides are, the more engaged your audience will be. A great way to spice up your bullet points or images in a slide is to not only add animation, but to also add audio to the animation.

5. Remove the Background from a Picture

The Remove Background feature in PowerPoint 2016 helps you eliminate distracting backgrounds so the important parts of your image are front and center. In a few simple steps, you can create praiseworthy presentations and nobody will ever know you did all that fancy image editing right within PowerPoint.

6. Insert a Screenshot or Screen Clipping

A PowerPoint deck is a prime example of an Office document that brings together many types of rich media. And when you have a presentation with more than 20 slides, importing files can be tedious and take a lot of time. To help ease the time on image importing, the built-in screenshot button can speed up your PowerPoint deck creation.

7. Embed YouTube Videos

Incorporating rich media in your PowerPoint presentation is a sure way to keep your audience more interested. In PowerPoint 2013/2016, it’s as simple as a few clicks to embed a YouTube video into a slide. Whether you’re embedding a specific video, or need a clip from a famous movie to use as an analogy, find the right video and load it in your presentation in a matter of seconds.

Result : Created and enhanced Power Point Presentation.

 

4th sem (4): Creating e-mail id and use of internet to send/ receive e-mails.

Aim : Create a Google Account

A Google Account gives you access to many Google products. With a 

Google Account, you can do things like:

• Send and receive email using Gmail

• Find your new favorite video on YouTube

• Download apps from Google Play

Diagram : 

Step 1: Choose a Google Account type

For myself To manage a business

Important: When you create a Google Account for your business, you 

can turn business personalization on. A business account also makes 

it easier to set up Google My Business, which helps improve your 

business visibility and manage your online information.

When you create a Google Account, we ask for some personal info. 

By providing accurate info, you can help keep your account secure 

and make our services more useful.

Tip: You don't need a Gmail account to create a Google Account. You 

can use your non-Gmail email address to create one instead.

1. Go to the Google account Sign In page.

2. Click Create account.

3. Enter your name.

4. In the "Username" field, enter a username.

5. Enter and confirm your password.

6. Click Next.

• Optional: Add and verify a phone number for your account.

7. Click Next.

Use an existing email address

1. Go to the Google Account Sign In page.

2. Click Create account.

3. Enter your name.

4. Click Use my current email address instead.

5. Enter your current email address.

Result: A google account has been created and you can sent messages and files via this mail address.

4th sem (3) : Measurement of voltages of given dry batteries of different voltages

 Aim: Measurement of voltages of given dry batteries of different voltages

Apperatus : Two dry batteries of different voltages

Diagram : 

Procedure :

1 Two dry cells have been taken whose voltages are different.say 1.5 V and 12 V.

 A digital multimeter have been taken to measure the voltage.

3 use of a proper scale in multimeter has been selected in multimeter so that can measure both the v.

4 Note down the voltages taken by multimeter.

Result: 

The voltages of two dry cell batteries are calculated as 1.5V and 9v respect.

4thSem: (2)To measure power of an appliance and calculate time for 1 kWh unit of electric energy consumption.

 Aim : To measure power of an appliance and calculate time for 1 kWh unit of electric energy consumption.

Diagram : 

Procedure:

To calculate the consumption of an electrical appliance in kWh, you have to take into account three factors:

the capacity of your electrical appliance, expressed in watt.
the number of hours that the appliance is in use in one day.
the number of days per year when the appliance is in use.

The calculation :

[number of  hours’ use] x [number of days’ use] x ([capacity of appliance expressed in watt] / 1,000) = number of kWh

The capacity should be divided by 1,000 to convert the number of watts into the number of kilowatts. This finally gives us the number of kWh (kilowatt hours).

Calculation for the energy consumption of a vacuum cleaner

In the table below we assume that

 the vacuum cleaner is used for two hours once a week.

hours / day	2 hours
days / year	52 days
Capacity of vacuum cleaner	2000 watts

Result : 

Annual energy consumption of vacuum cleaner is calculated as

208kWh

2 x 52 x(2,000 watts/1,000)=208 kWh.

4th sem: (1) Study of transformer and determination of turn’s ratio

Aim : Study of transformer and determination of turn’s ratio

Apperatus : transformer, Multimeter

Formula : Vp/Vs= np / ns

• Where:
•   VP  –  is the Primary Voltage
•   VS  –  is the Secondary Voltage
•   NP  –  is the Number of Primary Windings
•   NS  –  is the Number of Secondary Windings
•   Φ (phi)  –  is the Flux Linkage

Diagram : 

Theory and Calculations:

A voltage transformer has 1500 turns of wire on its primary coil and 500 turns of wire for its secondary coil.( Can change the no of turns)

The turns ratio (TR) of the transformer.

( Primary to secondary )

 

This ratio of 3:1 (3-to-1) simply means that there are three primary windings for every one secondary winding. 

As the ratio changes from a larger number on the left to a smaller number on the right, the primary voltage is therefore becomes less i.e stepped down in value as shown.

Therefore When a transformer is used to “increase” the voltage on its secondary winding with respect to the primary, it is called a Step-up transformer.

 When it is used to “decrease” the voltage on the secondary winding with respect to the primary it is called a Step-down transformer.

Result : Thus the basic structure of transformer has been studied and Turns ratio of primary to secondary  is calculated as 3:1.

The given case is of step down Transformer.
