Electricity Flashcard

Front

What is a parallel circuit?

Back

A circuit where receivers are connected to different branches, allowing multiple paths for current to flow.

Front

What is a series circuit?

Back

A circuit where components are connected in a single path, so the same current flows through all components.

Front

What opposes the flow of current in a circuit?

Back

Resistance.

Front

What charge does an electron have?

Back

Negative (-).

Front

How are flow rate and pipe resistance related?

Back

They are inversely related; as resistance increases, flow rate decreases.

Front

What is voltage?

Back

The electric potential difference between two points in a circuit.

Front

What is current?

Back

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

Front

What is Ohm's Law?

Back

The relationship between voltage (V), current (I), and resistance (R) in a circuit: V = I × R.

Front

What is a conductor?

Back

A material that allows electric current to flow easily, such as copper or aluminum.

Front

What is an insulator?

Back

A material that resists the flow of electric current, such as rubber or glass.
