Question

In the given circuit voltmeter shows a reading of 4V, then the power developed across R resistance will be I Is the answer 12mW

Answer 1

(3) 12mW is the right option✔

By assuming zero volt at one end of the battery=

across 2KΩ resistance = ΔV=IR

(10−4)=I×(2000)

6=I×(2000)

I= 6/2000

=3mA

Now power generated through resistance R= (voltage across resistance R)×(current flowing through resistance R)

P = 4×3 m W

P = 12 m W
