Electricity

Front

What is a conductor?

Back

A material that allows the flow of electric current, such as metals like copper and gold.

Front

What is an insulator?

Back

A material that resists the flow of electric current, preventing electricity from passing through, such as rubber or glass.

Front

What is electric current?

Back

The flow of electric charge in a circuit, measured in amperes (A).

Front

What is voltage?

Back

The electric potential difference between two points in a circuit, measured in volts (V).

Front

What is a circuit?

Back

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

Front

What is a parallel circuit?

Back

A type of circuit where there are multiple paths for current to flow, and the voltage across each component is the same.

Front

What is a series circuit?

Back

A type of circuit where components are connected end-to-end, so the current flows through each component in turn.

Front

How do you calculate current using power and voltage?

Back

Current (I) can be calculated using the formula I = P/V, where P is power in watts and V is voltage in volts.

Front

What is the formula for electrical power?

Back

Power (P) is calculated using the formula P = V × I, where V is voltage and I is current.

Front

What is resistance?

Back

The opposition to the flow of electric current, measured in ohms (Ω).
