Question

how to do numericals of connected in parallel and connected in series​

Answer 1

When connected in parallel do it in fraction form like,

1/r1+1/r2+1/r3

then take the reciprocal of the answer. that will be resistance. For series just add all of them together.

Answer 2

Answer:

When the combination is in parallel then use-

1/Rt = 1/R1 +1/R2 +1/R3.....and so on

Here Rt is total resistance

And R1, R2, R3.... Are all no of resistors..

HOPE it helps.
