B) 1 kilowatt | 1 किलोवाट
००००
C) 1 HP | 1 एचपी
OD) 1 Kilowatt hour | 1 किलोवाट घण्टा​

Answer 1

Given:

An emf of one volt causes a  current flow of 1ampere

To find:

What is the power if an emf of one volt causes a  current flow of 1ampere?

Solution:

From given, we have,

An emf of one volt causes the  current flow of 1ampere

⇒ E = 1 volt

⇒ I = 1 A

The formula for calculating the power given, the values of the emf and the current is as follows.

So, we have,

P = VI

P = 1 volt × 1 A

∴ P = 1 watt

Therefore, option (A) 1 watt is correct.
