Electricity & Circuits

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where components are connected across common points or junctions, allowing multiple pathways for current to flow. This ensures that all components receive the same voltage.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where components are connected end-to-end in a single path, so the same current flows through all components.

What happens to the brightness of bulbs in a parallel circuit?

Back

In a parallel circuit, all bulbs have the same brightness because they receive the same voltage.

Front

How many pathways does a series circuit have for electron flow?

Back

A series circuit has only one pathway for electrons to flow.

Front

What is the main advantage of a parallel circuit?

Back

The main advantage of a parallel circuit is that if one component fails, the others continue to operate.

Front

What is the main disadvantage of a series circuit?

Back

The main disadvantage of a series circuit is that if one component fails, the entire circuit is broken and all components stop working.

Front

What is the role of a battery in a circuit?

Back

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

Front

What is current?

Back

Current is the flow of electric charge, measured in amperes (A). It represents how many electrons pass a point in the circuit per second.

Front

What is voltage?

Back

Voltage is the electrical potential difference between two points in a circuit, measured in volts (V). It determines how much energy is available to push the current through the circuit.

Front

What is resistance?

Back

Resistance is the opposition to the flow of electric current, measured in ohms (Ω). It affects how much current will flow for a given voltage.
