Electrical Circuits

Front

What is an electrical circuit?

Back

An electrical circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

Front

What is the role of a battery in a circuit?

Back

A battery serves as the power source that provides the electrical energy needed to drive the current through the circuit.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where components are connected end-to-end, providing a single pathway for current to flow.

Front

What is a parallel circuit?

Back

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

Front

What happens if one component fails in a series circuit?

Back

If one component fails in a series circuit, the entire circuit is interrupted, and all components stop functioning.

Front

What happens if one component fails in a parallel circuit?

Back

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

Front

Define 'current' in the context of electrical circuits.

Back

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

Front

Define 'voltage' in the context of electrical circuits.

Back

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

Front

What is resistance in an electrical circuit?

Back

Resistance is 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): V = I × R.
