Question

The circuit diagram shown in Fig. 3.23 consists
i=4R = 12 and R3 = 24 2 and the
er ma potential difference of 12 V. Calculate:
the same of the circuit
the ding the ammeter, and
the
perence between the points K and L and
in the circuit resistances R, and R3 are joined in
aiven by​

Answer 1

Explanation:

Req = R + R + R + R = 4R ohm

Total current in the circuit, I = V/R = 12/4R = 3/R

Reading of voltmeter A = Voltage across R1 = I x R1 = 3/R x R = 3V

Reading of voltmeter B= Voltage across R2 = I x R2 = 3/R x R = 3V

Reading of voltmeter C= Voltage across the series combination of R3 and R4 = I x (R3+R4) = 3/R x 2R = 6V
