Question

In the circuit shown below, calculate the total resistance of the circuit and the current flowing through it

Answer 1

In the arm CE  

2 ohm and 4 ohm resistance are in series . Therefore total resistance in arm CE is 2 + 4 = 6 ohms.

Arm Ce and arm AB are parallel  

so total resistance of the circuit is :

1/Rtotal = 1/6 + 1/6

            = 2/6

Rtotal = 6/2= 3 ohms

(b) Total current drawn is :

V = I Rtotal

I = V/ Rtotal

I= 3/3 = 1Ampere
