Electricity & Circuits

Front

What is a parallel circuit?

Back

A type of circuit where components are connected across common points, allowing multiple pathways for current. All components have the same voltage, ensuring equal brightness in bulbs.

Front

What is a series circuit?

Back

A type of circuit where components are connected end-to-end, forming a single pathway for current. If one component fails, the entire circuit stops working.

Front

What happens in a series circuit if one component is disconnected?

Back

The entire circuit stops working because there is only one pathway for the current.

Front

How many pathways for electron flow are there in a series circuit?

Back

One pathway.

Front

What is the main advantage of a parallel circuit?

Back

It ensures that all components have the same voltage, allowing them to operate independently.

Front

What happens if one light bulb goes out in a parallel circuit?

Back

The other light bulbs remain lit because they have separate pathways for current.

Front

What is the definition of voltage?

Back

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

Front

What is current?

Back

Current is the flow of electric charge in a circuit, measured in amperes (amps).

Front

What is resistance?

Back

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

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 can be expressed as V = I × R.
