Question

write the formula for the effective resistance of 'n' resistors having resistance 'r' each if these are connected in
1)in series
2)in parallel​
pls reply

Answer 1

Answer:

For series... R1+R2+....... n=R.n

For parallel it will beR/n

Explanation:

Answer 2

Answer:

Explanation:

in series

Req=R1+R2+.......Rn

in parallel

1/Req=1/R1+1/R2+......1/Rn

it is because in series voltage will be different in parallel voltage will be same.

with those formulas we can derive these formulas
