Electric Circuits flashcard

Front

What is an electric circuit?

Back

An electric circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, components are connected end-to-end, so the current flows through each component one after the other. In a parallel circuit, components are connected across common points, allowing current to flow through multiple paths.

Front

What is a conductor?

Back

A conductor is a material that allows electric current to pass through it easily, such as copper or aluminum.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electric current, such as rubber or glass.

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

Back

The brightness of each bulb decreases because the total voltage is divided among all the bulbs.

Front

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

Back

The brightness of each bulb remains the same because each bulb receives the full voltage from the power source.

Front

What is the role of a switch in an electric circuit?

Back

A switch controls the flow of electricity in a circuit by opening (turning off) or closing (turning on) the circuit.

Front

What is the function of a battery in a circuit?

Back

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

Front

What is electric current?

Back

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

Front

What is voltage?

Back

Voltage is the electrical potential difference between two points in a circuit, measured in volts (V).
