Question

Which of the following is not equal to watt?
(a) joule/second
(b) ampere x volt
(c) (ampere)2 x ohm
(d)ampere/volt​

Answer 1

Explanation:

Your answer is :----> option (d )

As, Ampere / Volt = current/ Potential difference = I / V is not the formula for Power.

1. Joule / sec = Work done / time = power , so first option is equal to watt.

2. As , P = VI , watt = volt × Ampere , so , it is also equal to watt.

3. Also, P= I^ 2× R , which means watt = (Ampere)2 × ohm.

4. Fourth one is incorrect as Ampere/ volt is not equal to watt.
