Question

Calculate the amount of work done if a cell of 120 v passes current of 5A if in a ckt. for 10 second ?​

Answer 1

Answer:

The amount of work done is 6000 J.

Explanation:

➣ Given data:

• Volt (V) = 120 V
• Current (I) = 5 A
• Time (t) = 10 sec

➣ To find:

Amount of work done.

➣ Solution:

We know that,

I = Q/t

➪ Q = I × t

Now, V = W/Q

➪ W = V × Q

➪ W = V × (I × t)

= 20 × 5 × 10

= 6000 J.

Therefore 6000 J is the total amount of work done.
