Energy: Investigation 1

Front

What is a circuit?

Back

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

Front

What are the main parts of a circuit?

Back

The main parts of a circuit include a power source (like a D-cell), wires, a switch, and a load (like a light bulb).

Front

What is a D-cell?

Back

A D-cell is a type of battery that stores electrical energy and provides power to a circuit.

Front

What is the function of a switch in a 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 positive terminal of a D-cell?

Back

The positive terminal is the part of the D-cell where electric current flows out.

Front

What is the negative terminal of a D-cell?

Back

The negative terminal is the part of the D-cell where electric current flows in.

Front

What is a series circuit?

Back

A series circuit is a circuit where all components are connected in a single path, so the current flows through one component to get to the next.

Front

What is a parallel circuit?

Back

A parallel circuit is a circuit where components are connected across common points or junctions, allowing multiple pathways for the current to flow.

Front

What happens to the current in a series circuit if one component fails?

Back

If one component fails in a series circuit, the entire circuit stops working.

Front

What happens to the current in a parallel circuit if one component fails?

Back

If one component fails in a parallel circuit, the other components can still operate because there are multiple pathways for the current.
