Question

Establish a relationship to determine the equivalent resistance r of a combination of three register having resistance r1 r2 and r3 connected in series calculate the equivalent resistance of combination of three resistors of 2 ohm 3 ohm and 6 ohm died in parallel

Answer 1

resistance in series

r = r1 + r2 + r3

1/R = 1/2 + 1/3 + 1/6

6/R = 3 + 2 + 1

6R = 6

R = 1 Ohm
