Question

BEC unit 1 and 2 Question Bank For the circuit shown in below, determine (a) the battery voltage V, (b) the total resistance of the circuit, and (c) the values of resistance of resistors R1, R2 and R3, given that the p.d.'s across R1, R2and R3 are 5V, 2V and 6V respectively.​

Answer 1

Explanation:

(i) Total resistance of two resistors that are connected in parallel is

1/R

′

=1/3+1/6

1/R

′

=3/6

R

′

=2ohms

Total resistance of the circuit =2+4ohms=6ohms

(ii) Total current flowing through the circuit = V / total resistance

I=12/6=2amps

(iii) Potential difference across R

1

V=R

1

×I=4×2=8V.
