Question

Resistance of two resistors are 6 ohms 12 ohms ohms respectively. Find the resultant resistance if the resistors are connected i) in series ii) in parallel.​

Answer 1

Answer:

I) in series,

R = R1 + R2

= 6 + 12

R = 18 ohm

2) in parallel

1/R = 1/R1 + 1/R2

= 1/6 + 1/12

1/R = 1/4

R = 4 ohm
