Question

Two the identical resistors, each of resistance 2 ohm, are connected in turn : thin wies and
battery of 12 V. Calculate the ratio of powers consumed in two cases.​

Answer 1

ANSWER

a)in series=2+2=4ohm

I=V/R=12/4=3

P=I2R=(3)2*4=36

b)in parallel=1/2+1/2=1

I=V/R=12/1=12

P=I2R=(12)2*1=144

c)ratio=36/144=1/4=1:4

therefore ratio =1:4
