What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where the components are connected across common points or junctions, providing multiple paths for current to flow.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which components are connected end-to-end, so that the same current flows through each component.

Front

What is the flow of electricity?

Back

Electricity is the flow of electrons.

Front

What happens to current in a series circuit?

Back

In a series circuit, the same current flows through all components.

Front

What happens to current in a parallel circuit?

Back

In a parallel circuit, the total current is divided among the parallel branches.

Front

What is resistance in a circuit?

Back

Resistance is a measure of the opposition to the flow of electric current, measured in ohms (Ω).

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 is expressed as V = I × R.

Front

What is a light bulb in a circuit?

Back

A light bulb is a device that converts electrical energy into light energy, typically using a filament that glows when current passes through it.

Front

What is a battery's role in a circuit?

Back

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

Front

What is a short circuit?

Back

A short circuit occurs when there is a low-resistance connection between two points in a circuit, allowing excessive current to flow, which can cause damage.
