What is an electric circuit?
An electric circuit is a complete path that allows the flow of electrons from one point to another.
What is the difference between AC and DC current?
AC (alternating current) constantly changes direction
While DC (direct current) flows in only one direction.
What is a conductor?
A conductor is a material that easily conducts electricity, such as copper or aluminum.
What is an insulator?
An insulator is a material that does not conduct electricity, such as rubber or plastic.
What is resistance?
Resistance is a property of a material that resists the flow of electricity.
What is a resistor?
A resistor is a device that controls the flow of electricity by providing resistance.
What is the unit of electric current?
The unit for electric current is amperes (A).
What is the unit of electric charge?
The unit for electric charge is coulombs (C).
What is a battery? 🔋
A battery is a device that converts chemical energy into electrical energy.
What is a switch?
A switch is a device that can be used to turn a circuit on or off.
What is a fuse?
A fuse is a device that protects a circuit from overloading and overheating.
What is a circuit breaker?
A circuit breaker is a device that automatically switches off a circuit when there is a fault.
What is an electromagnet?
An electromagnet is a magnet that is created by passing an electrical current through a coil of wire.
