Question

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

Answer 1

Answer:

In order to get total resistance as 9ohm u should first connect two resistors in parallel to each other and the third resistor in series.

Explanation:

R1+R2=6×6/6+6=3 ohm

R3=6ohm

R1+R2+R3=9 ohm

•In order to get the total resistance as 4 ohm , u should connect to resistors in series and the third resistor in parallel to the other two resistors.

R1+R2=6+6+=12ohm

R3=6ohm

12×6/12+6=72/18=4ohm
