Wistron Diploma Electronics Engineer Interview Questions and Answers

Resistance is the opposition to the flow of electric current in a circuit.

• Resistance is measured in ohms (Ω).

• It is caused by the collisions of electrons with atoms in a material.

• Higher resistance leads to lower current flow in a circuit.

• Resistance can be affected by factors like material, length, and temperature.

• Example: A light bulb has resistance that converts electrical energy into light and heat.

Inductance is the property of an electrical circuit that opposes changes in current flow.

• Inductance is measured in Henry (H)

• It is caused by the magnetic field generated when current flows through a conductor

• Inductors are components that are designed to have a specific inductance value

• Inductance is used in filters, transformers, and motors

Capacitance is the ability of a system to store an electric charge.

• Capacitance is measured in Farads (F).

• It is the ratio of the electric charge stored on a conductor to the potential difference across it.

• Capacitors are electronic components that are designed to store and release electrical energy.

• Capacitance is used in various applications such as filtering, energy storage, and timing circuits.

Electricity can be produced through various methods such as burning fossil fuels, harnessing renewable energy sources like wind and solar, or using nuclear reactions.

• Burning fossil fuels like coal, oil, and natural gas in power plants to generate steam that drives turbines connected to generators.

• Harnessing renewable energy sources like wind turbines to convert kinetic energy into electricity.

• Using solar panels to conv...read more
