The current in a single-loop circuit containing a single resistance R is 6 amps. When an additional resistance of 12 Ω is inserted in series with R, the current drops to 3 amps. What is R?
Solution)
Given,
Current, I1=6 A
Resistance, R2=12 ohms
Current, I2=3 A
According to Ohm's law, we can conclude
I1*R1= I2*R2
Substitute values,
6*R=3*(R+12)
Since, 12 ohms connected in series with R
So, 6R=3R + 36
3R=36
Resistance, R=12 ohms (Ans)
