Question

Find the work done to move a charge of 4 coulomb from 40 volt to 220 volt.​

Answer 1

Answer:

∴ ΔV=10 volts.

Amount of charge moving q=4 coulombs.

Thus work done W=qΔV.

∴ W=4×10=40 Joules.

Answer 2

Answer:

Calculate the wor

Potential difference = V2 – V1 =230V – 220V = 10 V.

So as we know that.

Work done = Potential difference × Charge moved.

= 10 × 4 = 40 joule.

So, the work done in moving a charge of 4 coulombs from a point at 220 volts to another point at 230 volts is 40 Joule.

Thus work done W=qΔV

∴ W=4×10=40 Joules
