Question

Find the odd one

P=VQ/T
P=W/T
P=V2R
P=IR​

Answer 1

Answer:

The odd one is P = VQ/T

All the other expressions of power are correct.

Answer 2

Correct Question:

Find the odd one

P=VQ/T

P=W/T

P=V²/R

P=IR​

Correct Answer:

The odd one is:

P = IR​

- Power can be given as:

P = VI      ......(i)

- We know that current, I = Q/T

- Put I = Q/T in (i), we get:

P = VQ/T

- Power can also be defined as the work done per unit time:

P = W/T

- Put I = V/R in (i), we get:

P=V²R

- So, all these three denote the same quantity, i.e., Power.

- Whereas P = IR is incorrect and hence the odd one.
