Question

Find the equivalent resistance between a and b of the circuit given below and current supplied by the battery in the circuit ( PLEASE EXPLANATION ALSO )

Answer 1

last two resistance of 4ohm are not a part of circuit so ignore them and calculate equivalent resistance

4 and 2 in series 6ohm

6and 3 in parallel 2ohm

again 4 and 2 in series 6ohm

6 and 3 in parallel 2ohm

equivalent resistance=6ohm

Answer 2

Ans:  Eq. resistance = 6 ohm

Explanation:

Since the final two 4 ohm resistors are not necessary for the circuit, ignore them and determine the equivalent resistance.

2 and 4 in a series of 6 ohms

parallel 6 and 3 2 ohm

likewise in series 6 ohm, 4 and 2

6 and 3 together 2ohm

6 ohm is the equivalent  resistance.
