Electricity and Magnetism

Front

What is a series circuit?

Back

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

Front

What happens if one component in a series circuit fails?

Back

If one goes down, they all go down!

Front

What is a solenoid?

Back

A coil of wire that generates a magnetic field when an electric current passes through it.

Front

What is current measured in?

Back

Amperes.

Front

What is electricity?

Back

The flow of electrons.

Front

What is a parallel circuit?

Back

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

Front

What happens if one component in a parallel circuit fails?

Back

The other components can still operate.

Front

What is voltage?

Back

The electric potential difference between two points, measured in volts.

Front

What is resistance?

Back

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

Front

What is Ohm's Law?

Back

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