Expert Answer
Potential across resistors R1, R2 and R3,
Potential difference across the circuit is 6 V.
The equivalent resistance in the circuit is
12 ohms resistors are connected in parallel.
Thus,
Rp = 1/12 + 1/12 = 6 ohms
Thus,
Req = 6 +6 = 12 ohms.
Thus, the
Total current in the circuit is,
V = IR
6 = I x 12
I = 6/12 = 0.5 A
Thus, the Potential difference across,
R1 = 6 ohms is,
V = I R
V = 0.5 x 6 = 3 V
Thus,
Potential difference across R2 is,
V = Vs + Vp
Vp =6 - 3 = 3 V
As the R2 and R3 are connected in parallel the potential difference across the R3 will be same as that across R2.
Thus potential difference across R3 = 3 V
