Series & Parallel Circuits

Front

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

Back

The total resistance will increase.

Front

What is the symbol for a switch?

Back

A switch is represented by a specific symbol in circuit diagrams.

Front

What is true about the current through each resistor connected in series?

Back

The current is the same everywhere.

Front

What is needed in a circuit to start the electrons moving?

Back

A power source is needed.

Front

What happens to the voltage across a resistor in series as its resistance increases?

Back

The measured voltage across that resistor will increase.

Front

What is a circuit?

Back

A circuit is a closed path through which electric current flows.

Front

What is a resistor?

Back

A resistor is a component that resists the flow of electric current.

Front

What is the difference between series and parallel circuits?

Back

In series circuits, components are connected end-to-end, while in parallel circuits, components are connected across common points.

Front

What happens to the total current in a parallel circuit?

Back

The total current is the sum of the currents through each parallel branch.

Front

What is a battery?

Back

A battery is a power source that provides electrical energy.
