Question

show how would you join three resistors each of resistors each of resistance 9ohm's​

Answer 1

Explanation:

HEY MATE ..

Resistance of each resistor R=9ΩTwo resistor connected across A and B are connected in parallel.Equivalent resistance across A and B Rab =

R × R / R + R = R /2 = 9 /2 = 4.5Ω

This equivalent resistance is connected in series to another resistor R.So equivalent resistance across A and C

R ac = R ab + R =4.5 + 9 = 13.5Ω
