Question

5 ohm, 10 ohm and 15 ohm, what is the equivalent resistance if we add three values ​​of resistance to the series connection and then to the parallel connection?​

Answer 1

Answer:

Series

R1 + R2 + R3 = R(eq)

5+10+15=30 ohm

Parallel

1/R1 + 1/R2 + 1/R3 = 1/R(eq)

1/10 + 1/5 + 1/15 = R(eq)

LCM 30

3/30+6/30+2/30=11/30 Ohms
