Question

formula of total circuit resistance?

Answer 1

In series:
_______


Rs=R1+R2+R3.....
depends on how many resistors there are..

○●●●●●●●●●●●●●●●●●●○

In parallel:
________

1/Rp=1/R1+1/R2+1/R3...

Also depends on how mamy resistors there are.....

hope it helps u!!☺☺☺☺☺

Answer 2

there are two formaulas for equivalent resistance of the circuit.
in series it is Rs=R1+R2+R3.......
in parallel it is
$\frac{1}{rp } = \frac{1}{r1} + \frac{1}{r2} + \frac{1}{r3} .......$
it is the answer
