Question

Five equal resistors when connected in series dissipated 5w power. If they are connected by parallel, the power dissipated will be select one: a. 25w b. 50w c. 100w d. 125w

Answer 1

hi here your answer

I think the answer is b 50

Answer 2

Answer:125W

Explanation:let voltage be "V" and resistors are of 1ohm each

V^2/5 = 5W

or, V^2 = 25

or, V=5

Now resistors are connected in parallel so,

R=1/5

and, V^2/(1/5) = x

or, 25/(1/5) = x

or, x = 125W
