A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers are used to increase or decrease the voltage levels in electrical power transmission and distribution systems.

• They consist of two or more coils of wire, known as windings, which are wound around a core made of magnetic material.

• The primary winding is connected to the input v...read more

Current in a motor can be found using an ammeter.

• Connect the ammeter in series with the motor

• Turn on the motor and measure the current

• Current can be found using the formula I = V/R

• Use a clamp meter to measure current without breaking the circuit
