Question

Find the odd one from the group and give reason for your selection?

(I2R, VI, V2
/R, IR2
)​

Answer 1

Answer:

IR^2

Explanation:

THEIR IS NO UNIT LIKE THAT

Answer 2

Answer:

Among the given option the odd one is $IR^{2}$ as power cannot be written in this format.

Explanation:

For solving this question we first need to know what is power. So, first, let's define electric power.

Electric power- it measures the rate of electrical energy transferred by an electric circuit per unit of time. It is commonly supplied by electric batteries and produced by electric generators.

Or simply we can say that it is a measure of how much energy is used in a span of time.

Formula,

P=V×I    (1)

Where,

P=power

V=potential across the circuit

I= current flowing through the circuit

Also,

V=I×R   (2)

R=Resistance of the circuit

By using equation (2) we can write equation (1) we get;

P=$(I)^{2}$×R    (3)

we can also write equation (2) as,

I=V$/$R     (4)

By using equation (4) we can write equation (1) as;

P=$(V)^{2} /R$   (5)

Hence, among the given option the odd one is $IR^{2}$ as it is incorrect.
