... When Michael Faraday made his discovery of electromagnetic induction in 1831, he hypothesized that a changing magnetic field is necessary to induce a current in a nearby circuit. To test his hypothesis he made a coil by wrapping a paper cylinder with wire. He connected the coil to a galvanometer, an ...

... Experiment was carried out to demonstrate that when a current passes through a resistor, the resistor will glow and gives out heat and light. When an electric current passes through a resistance coil, the electric energy is converted into heat energy. This is known as the heating effect of current. ...
