Question

c)What is the effective resistance in the given circuit?​

Answer 1

Explanation:

1. The effective resistance of a circuit containing resistances in parallel is smaller than any of the individual resistances. For example : R1=2Ω and R2=3Ω ∴ Effective resistance Rp1=R11+R21. OR Rp1=21+31 Rp=1.
2. Maximum effective resistance will be when all the resistors are in series combination. So, Reffmax=n R. Minimum effective resistance will be when all the resistors are in parallel combination.

Answer 2

Answer:

R total = R1 + R2

R total = 2 + 2 = 4 ohm
