Question

Find the effective resistance of the combination of two resistors of

resistance 30 and 15 connected in series.​

Answer 1

Answer:

Combination of parallel resistors can be calculated as below,

1/R =1/r1 + 1/r2 +….. + 1/rn

Where r1, r2 are the resistors which are connected in parallel,

So according to above formula

We have,

Req=30*15/90 = 5.
