A quick tool to calculate total resistance in a parallel circuit with up to 20 resistors. This is my first project using C++. I'm certain the code is horribly inefficient, but I'm not yet familiar ...

When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. When resistors are connected in series ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.
