#### Induction Motor

It is a self starting electric motor which operates on induction principle. The magnetic field produced in the stator induces a current in the rotor winding to produce required torque.

#### DC SeriesĀ Motor

It is a self excited DC motor which converts electrical energy into mechanical energy. In this the series winding is connected in series with armature winding.

#### Synchronous Generator

It is an important electrical component which converts mechanical energy into electrical energy. It is mostly used in power plants to generate the electricity in synchronous with other generators.

#### Electrical Fuse Practice Tests

It is a low resistance wire which acts as a over current protection device forĀ an electrical circuit. basically thin wire melts if over current flows through it.

##### Ohm’s law quiz questions

Ohms law states that in an electrical circuit the current flow is proportional to driving potential applied to the circuit. i.e if the voltage applied to the circuit increases then the current flow in the circuit increases.
