Circuits, electricity, and magnetism

Front

What happens when an electric current flows in a wire?

Back

A magnetic field is created.

Front

What is an example of a resistor?

Back

Light bulb.

Front

What is a series circuit?

Back

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

Front

What happens to a compass needle placed under a wire with current flowing from north to south?

Back

It rotates because of a magnetic force that acts on the needle.

Front

How are electric and magnetic forces related?

Back

Both the electric and magnetic forces are caused by the motion of charged particles such as electrons.

Front

What is the definition of electric current?

Back

The flow of electric charge, typically measured in amperes.

Front

What is a parallel circuit?

Back

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

Front

What is Ohm's Law?

Back

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

Front

What is the role of a battery in a circuit?

Back

A battery provides the voltage needed to push electric current through the circuit.

Front

What is a magnetic field?

Back

A region around a magnet where magnetic forces can be detected.
