In a parallel circuit, the total resistance (Rt) can be determined using the following formula:
1/Rt = 1/r1 + 1/r2 + 1/r3
where r1, r2, and r3 are the individual resistances of the components in the parallel circuit.
By taking the reciprocal of each resistance, adding them together, and then taking the reciprocal of the sum, you can find the total resistance of the parallel circuit.
I hope this helps. Cheers! ^^
