What is a series circuit?

Back

A series circuit is a type of electrical circuit where there is only one path for current to flow. If one component fails, the entire circuit stops working.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit that has multiple paths for current to flow. If one component fails, the current can still flow through other paths.

What is resistance in a circuit?

Back

Resistance is a measure of how much a material opposes the flow of electric current. It slows down the flow of electricity.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical circuit through which current can flow. It has no breaks or gaps.

Front

What is an open circuit?

Back

An open circuit is a circuit that is not complete, meaning there is a break or gap that prevents current from flowing.

Front

What is the role of a power source in a circuit?

Back

A power source provides the electrical energy needed to push the current through the circuit.

Front

What happens when you add more resistors in series?

Back

Adding more resistors in series increases the total resistance of the circuit, which decreases the overall current.

Front

What happens when you add more resistors in parallel?

Back

Adding more resistors in parallel decreases the total resistance of the circuit, which increases the overall current.

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.

Front

What is a conductor?

Back

A conductor is a material that allows electric current to flow through it easily, such as copper or aluminum.
