The current is different in different parts of a parallel circuit. In most buildings, the lights and sockets are all connected in big circuits but you can switch individual devices off ...

Currently, most spintronic devices are based on ferromagnets ... can function as "electrical circuits" with the two magnetic sublattices connected in parallel. With this simple intuitive picture ...

We examine how to find the total voltage, current and resistance of parallel and complex circuits. We also use a V.I.R. chart to find these things across individual resistors within a circuit.

Moreover, the mechanical logic gates and circuits can be executed simultaneously, giving rise to the prospect of a parallel logic processor in just a single mechanical resonator.
