Electrical Circuit Symbols

Front

What does the symbol of a battery represent in an electrical circuit?

Back

A battery is a device that stores electrical energy and provides a voltage to drive current through a circuit.

Front

Will the light bulb in a circuit light if the switch is open? Why or why not?

Back

No, because the switch is open, which means the circuit is incomplete and current cannot flow.

Front

What is the term for a continuous flow of electricity?

Back

Current.

Front

What does a diode symbol represent in an electrical circuit?

Back

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

Front

What does the symbol of a resistor represent?

Back

A resistor is a component that resists the flow of electric current, creating a voltage drop.

Front

What is the function of a capacitor in an electrical circuit?

Back

A capacitor stores electrical energy temporarily and releases it when needed.

Front

What does the symbol for an open switch indicate?

Back

An open switch indicates that the circuit is incomplete and current cannot flow.

Front

What is the purpose of a fuse in an electrical circuit?

Back

A fuse protects the circuit by breaking the connection if the current exceeds a certain level.

Front

What does the symbol for a ground connection represent?

Back

A ground connection provides a safe path for excess current to flow into the earth, preventing electrical shock.

Front

What is the role of an inductor in an electrical circuit?

Back

An inductor stores energy in a magnetic field when current flows through it.
