Question

find the potential difference across R¹,R²,R³​

Answer 1

Answer:

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.
