Series & Parallel Circuits

Front

What does the symbol for a resistor represent in a circuit?

Back

A resistor is a component that opposes the flow of electrical current.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where the current has only one loop to flow through.

Front

What is the definition of electrical current?

Back

Electrical current is the rate of flow of charge.

Front

Which circuit configuration typically has brighter bulbs, series or parallel?

Back

Parallel circuits typically have brighter bulbs because each bulb receives the full voltage.

Front

What does the symbol for a wire represent in a circuit?

Back

A wire is a conductor that allows electrical current to flow between components.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where the current can flow through multiple paths.

Front

What happens to the total resistance in a series circuit when more resistors are added?

Back

The total resistance increases when more resistors are added in series.

Front

What happens to the total resistance in a parallel circuit when more resistors are added?

Back

The total resistance decreases when more resistors are added in parallel.

Front

What is the role of a battery in a circuit?

Back

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

Front

What is the function of a switch in a circuit?

Back

A switch is used to open or close a circuit, controlling the flow of current.
