a battery of 12v supplies a charge of 1000C to an electric device. how much work is done by the battery in moving the charge?

(1/2) C V^2 = 72000 J

In this question

We have v=12
Q=1000c
Now we know v=w/Q
W=Q×v
=12×1000
=12000joule

To calculate the work done by the battery in moving the charge, you can use the formula:

Work (W) = Electric Potential Difference (V) * Charge (Q)

In this case, the electric potential difference is given as 12V and the charge is given as 1000C.

Substituting the given values into the formula:

W = 12V * 1000C

W = 12,000 Joules

Therefore, the work done by the battery in moving the charge is 12,000 Joules.

To calculate the work done by the battery in moving the charge, we can use the formula:

Work (W) = Charge (Q) * Voltage (V)

Given:
- Charge (Q) = 1000 C
- Voltage (V) = 12 V

Substituting the values into the formula:

Work (W) = 1000 C * 12 V

Now let's calculate the work:

W = 1000 C * 12 V
W = 12,000 Joules (J)

Therefore, the battery does 12,000 Joules of work in moving the charge.
