Electric Circuits

Front

What is an electric circuit?

Back

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

Front

What is a conductor?

Back

A conductor is a material that allows electrons to flow easily, such as copper or aluminum.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electric current, such as rubber or glass.

Front

What happens in a series circuit if one component fails?

Back

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

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where components are connected across common points, allowing current to flow through multiple paths.

Front

What is the role of a battery in a circuit?

Back

A battery serves as an energy source, providing the electrical energy needed to power the circuit.

Front

What is 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): V = I × R.
