Diode, current, resistor, capacitor, forward bias, reverse bias, motor are basic components of electronics.

• Diode is a semiconductor device that allows current to flow in one direction.

• Current is the flow of electric charge.

• Resistor is a component that resists the flow of current.

• Capacitor is a component that stores electric charge.

• Forward bias is when the voltage applied to a diode allows current to flow through it.

• Reverse bias is when the voltage applied to a diode prevents ...read more

Current is the flow of electric charge through a conductor.

• Current is measured in amperes (A)

• It is the rate of flow of electric charge

• Direct current (DC) flows in one direction, while alternating current (AC) changes direction periodically

Resistors are electronic components that limit the flow of electric current in a circuit.

• Resistors are used to control the amount of current flowing in a circuit.

• They are measured in ohms (Ω) and come in various values.

• Resistors can be fixed or variable depending on the application.

• Examples include carbon film resistors, metal film resistors, and variable resistors like potentiometers.

A diode is a semiconductor device that allows current to flow in one direction only.

• Semiconductor device

• Allows current flow in one direction only

• Commonly used in rectifiers and voltage regulators
