Unit 5 ELECTRICITY and MAGNETISM

Front

What is a closed circuit?

Back

A closed circuit is a complete and unbroken path through which electric current can flow.

Front

What does the electronic schematic symbol for a wire represent?

Back

The electronic schematic symbol for a wire represents a conductor that connects different components in a circuit.

Front

What happens to the brightness of bulbs in a parallel circuit when more bulbs are added?

Back

The brightness remains the same because each bulb has its own path to the power source.

Front

What is the effect of opening switch 1 in a circuit with blue and other colored bulbs?

Back

Opening switch 1 results in only the blue bulbs working.

Front

If switch 2 is opened, which light does not work in a circuit with multiple colored bulbs?

Back

The blue light does not work when switch 2 is opened.

Front

Define electric current.

Back

Electric current is the flow of electric charge, typically measured in amperes (A).

Front

What is the difference between an open circuit and a closed circuit?

Back

An open circuit has a break in the path, preventing current from flowing, while a closed circuit allows current to flow uninterrupted.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where multiple paths exist for current to flow.

Front

What is the function of a battery in a circuit?

Back

A battery provides the electrical energy needed to drive the current through the circuit.

Front

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

Back

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