Question

Calculate the following in the given electric circuit:
a) Effective resistance of the circuit
b) Current flowing through 4 Ω resistor
c) Difference in ammeter readings, if any.

Answer 1

Explanation:

a) 8ohm and 8 ohm are in parallel

R equivalent. =. 1/R1. +. 1/R2

1/8 +. 1/8

4

4ohm

4ohm and 4ohm are in series

R equivalent = 8ohm

b) current (I) = v/r

I. = 8v/8

I. =. 1 ampere

so current through 4ohm resistor is 1 ampere

c). ammeter reading is same
