Question

observe Circuit. The power consumed by register
R2 is P. The power consumed by resistor
R1 when resistance R is removed from the circuit is ______ take R1 =R2
​

Answer 1

Answer:

Explanation:total resistance is 1/R1+1/R2

=2/R

V=IR HERE R=2/R SO

V=I×2/R

I=2V/R

IN SECOND CASE THERE IS ONLY ONE RESISTER SO

I=VR

NOW,

POWER IN FIRST CASE IS

P=IV

P=(2V/R)×V (I=2V/R)

P=2V^2/R

P=》》2(V^2/R)《《

POWER IN FIRST CASE IS

P=IV

》》P=(V^2/R)《《

IT MEANS POWER CONSUPTION

REDUCED TO HALF WHEN ONE OF THE RESISTER IS REMOVED

Sorry that i can't exapin you well as i have very less time
