# Current & Voltage In A Circuit watch

1. Hey guys I've gotten myself confused again! (This happens a lot)
Say in a circuit, the wire splits in to two different paths, would the voltage and current both half.
I think I remember that one of them will half but the other won't
2. Current will split, so to speak, and recombine at the end of the loops, whereas p.d. should be the same for each loop in a circuit.

Kirchoffs Second Law applies around loops, so if you had two loops or two resistors in parallel against a cell with negligible resistance and EMF of 5V, each resistor has the p.d. of 5V. If the resistors had a resistance of 1 ohm each, the total resistance of the circuit would be (1/1 + 1/1)^-1 = 1/2; 5/1/2 = 10 amps of current, which would split equally down the two loops.

Either way, current splits, and use Kirchoffs Second for loops. I hope I helped!
