Sodexo Electrical Technician Interview Questions, Process, and Tips

Current is the flow of electric charge in a circuit.

• Current is measured in amperes (A).

• It is the rate at which electric charge flows through a conductor.

• Current can be either direct current (DC) or alternating current (AC).

• In a DC circuit, the current flows in one direction only.

• In an AC circuit, the current changes direction periodically.

• Current is caused by the movement of electrons or other charged particles.

• It is e...read more

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 in an electrical circuit.

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

• The primary winding is connected to the power source, while the secondary winding is con...read more

A capacitor is an electronic component that stores and releases electrical energy.

• A capacitor consists of two conductive plates separated by an insulating material called a dielectric.

• When a voltage is applied across the plates, one plate accumulates positive charge while the other accumulates negative charge.

• Capacitors are commonly used in electronic circuits for energy storage, filtering, timing, and coupling.

• They ca...read more

A fuse is a safety device that protects electrical circuits from excessive current flow.

• A fuse is a small, thin wire or strip of metal that melts when excessive current flows through it.

• When a fuse melts, it breaks the circuit and prevents further flow of current, protecting the electrical equipment.

• Fuses are commonly used in electrical systems to prevent damage from short circuits or overloads.

• They are rated for speci...read more
