Question

heat energy is being produced in a resistance in a circuit at the rate of 100 W the current of 3 A is flowing in the circuit what must be the value of a resistance??

Answer 1

P = Vi ........... (V= iR)
P = iR×i = i^2R
R = P / i^2
R = 100/9 = 11.1 ohm

Answer 2

Answer:

power - 100 w

I - 3A

v -?

using

Explanation:

p = vI .

100 = v× 3

v= 33.3 v

now ,

by ohm's law ,

v = IR

33.3 = 3 × R

R = 11.1 ohm

R = 11 ohm

hence, the value os resistance is 11 ohm
