how do i find the restance of a paralell circut?

Answer 1

If you have one or more resistor in parallel, to find the overall, resistance of the circuit you must find the equivalent resistance of the resistors in parallel.

R_eq = equivalent resistance
R_x = resistance of the x resistor

1/R_eq = 1/R_1 + 1/R_2 + 1/R_3 + ..... and so on

To find the equivalent resistance, add the inverse of the all the individual resistances, then take the inverse of the whole thing.

For example, if you only had 2 resistors in parallel,
1/R_eq = (1/R_1 + 1/R_2)^-1
R_eq = (R_1 * R_2) / (R_1 + R_2)

Answer 2

.Use and ohmmeter, I need the points.
