Physical Science Circuit Review

Front

What is a battery?

Back

A battery is a device that stores electrical energy and provides power to a circuit.

Front

What is resistance in a circuit?

Back

Resistance is a measure of the opposition to the flow of electric current, measured in ohms.

Front

What is the total resistance in a series circuit?

Back

In a series circuit, the total resistance is the sum of the individual resistances.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which components are connected end-to-end, so that the current flows through each component in turn.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit in which components are connected across common points or junctions, allowing current to flow through multiple paths.

Front

What happens when a switch is closed in a circuit?

Back

When a switch is closed, it completes the circuit, allowing electricity to flow and power the devices connected.

Front

What is a resistor?

Back

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

Front

What is the function of a light bulb in a circuit?

Back

A light bulb converts electrical energy into light energy when current flows through it.

Front

What is the role of wires in a circuit?

Back

Wires provide a conductive path for electric current to flow between components.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). It is expressed as V = I × R.
