Question

Show how would you connect three resistors , each of resistance 10 Ω so that the
combination has a resistance of (a) 15 Ω (b) 6.67 Ω

Answer 1

Explanation:

Show how you would connect three resistors, each of resistance 6 Ω, so that the combination has a resistance of (i) 9 Ω, (ii) 4 Ω. The third 6 Ω resistor is in series with 3 Ω. Hence, the net resistance of the circuit is 6 Ω + 3 Ω = 9 Ω. ∴ the total resistance is 4 Ω.

this is your answer
