Circuits

Front

What are the components of a simple electric circuit?

Back

A simple electric circuit consists of a power source (like a battery), conductors (wires), and a load (like a light bulb or bell).

Front

What is the role of a battery in a circuit?

Back

The battery provides the electrical energy needed to power the circuit.

Front

What happens when a circuit is closed?

Back

When a circuit is closed, electricity flows through the circuit, allowing the components (like bulbs or bells) to operate.

Front

What is sound energy in the context of circuits?

Back

Sound energy is the energy produced by vibrating objects, such as bells in a circuit.

Front

What is the effect of adding more bulbs in a series circuit?

Back

Adding more bulbs in a series circuit increases the total resistance, which can decrease the brightness of each bulb.

Front

What is the difference between series and parallel circuits?

Back

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

Front

What is required to complete a circuit?

Back

A complete circuit requires a closed loop, allowing current to flow from the power source through the load and back.

Front

What is the function of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit by opening (breaking) or closing (completing) the circuit.

Front

How does resistance affect current in a circuit?

Back

Resistance opposes the flow of current; higher resistance results in lower current for a given voltage.

Front

What is a short circuit?

Back

A short circuit occurs when electricity flows along an unintended path, often causing excessive current and potential damage.
