If I pass electricity through heating coils will it make heat?
Yes, connecting a heating coil (a section of high heat output wire like nichrome or similar) to regular copper wires and a power supply properly will create heat. It will be proportional to how much power in Volts * Amps you put through it. A significantly weak supply will produce heat in wasted power, though it may be too small to register. A significantly strong supply may produce enough heat to melt the coil or wires.

It highly depends on the coil and supply used.
