Electric Circuits

Front

What is an open circuit?

Back

An open circuit is a circuit that is not complete, meaning that the current cannot flow because there is a break in the path.

Front

What is a closed circuit?

Back

A closed circuit is a complete circuit that allows current to flow without interruption.

Front

What is the function of a switch in a circuit?

Back

The function of a switch is to turn on and off the flow of current in a circuit.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where there are multiple paths for the current to flow.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where the current flows through one path, and all components are connected in a single loop.

Front

What is a fuse?

Back

A fuse is a safety device that protects a circuit by breaking the connection if the current exceeds a certain level.

Front

What is a circuit breaker?

Back

A circuit breaker is an electrical device that automatically interrupts the flow of current in a circuit when it detects an overload.

Front

What is a GFCI?

Back

A GFCI (Ground Fault Circuit Interrupter) is a device that protects against electrical shock by shutting off the circuit when it detects an imbalance in the current.

Front

What is an LED?

Back

An LED (Light Emitting Diode) is a semiconductor device that emits light when an electric current passes through it.

Front

What happens when you add more light bulbs in a series circuit?

Back

When you add more light bulbs in a series circuit, the total resistance increases, and the brightness of each bulb decreases.
