Question

formula of effective resistance​

Answer 1

Answer:

The sum of the currents through each path is equal to the total current that flows from the source. You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 +...

Answer 2

Answer:

Rs= R1 + R2 + R3 ( For resistors connected in series )

and

Rp= 1/R1 + 1/R2 + 1/R3 ( For Parallels resistors)
