Front

What is electrical current defined as?

Back

The continuous flow of electrons (charge)

Front

What type of circuit does not turn on a light bulb?

Back

An open circuit

Front

What does conductivity measure?

Back

How well a material conducts electricity

Front

What type of circuit allows for the complete flow of electrons from the negative end of the battery to the positive?

Front

What is the symbol for electrical current?

Back

I

Front

What is the relationship between voltage, current, and resistance?

Back

Ohm's Law: V = I × R

Front

What is a series circuit?

Back

A circuit where components are connected in a single path, so current flows through each component.

Front

What is a parallel circuit?

Back

A circuit where components are connected across common points, allowing multiple paths for current.

Front

What is resistance in an electrical circuit?

Back

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