If current =1.414 A and resistance = 50Ω, then find power
Question

If current =1.414 A and resistance = 50Ω, then find power

A.

400 Watts

B.

300 Watts

C.

100 Watts

D.

200 Watts

Correct option is C

Given, current (I)=1.414 A=2 A,Resistance (R)=50ΩP=I2R=(1.414)2×50=(2)2×50=2×50=100 watt=100 watt\text{Given, current } (I) = 1.414 \text{ A} = \sqrt{2} \text{ A}, \\\text{Resistance } (R) = 50\Omega \\P = I^2 R = (1.414)^2 \times 50 \\= (\sqrt{2})^2 \times 50 = 2 \times 50 = 100 \text{ watt} \\= 100 \text{ watt}​​
