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 component fails, the entire circuit is broken and all components stop working.

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 function, as the current can flow through the remaining paths.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. It can be expressed as V = I × R.

Front

How do you calculate current in a circuit?

Back

Current (I) can be calculated using the formula I = V / R, where V is voltage and R is resistance.

Front

What is voltage?

Back

Voltage is the electric potential difference between two points in a circuit, measured in volts (V). It is the force that pushes electric charges through a conductor.

Front

What is resistance?

Back

Resistance is a measure of the opposition to the flow of electric current, measured in ohms (Ω).

Front

What is a switch in a circuit?

Back

A switch is a device that can open or close a circuit, controlling the flow of electricity.

Front

What is a light bulb in a circuit?

Back

A light bulb is a device that converts electrical energy into light energy, typically using a filament or LED.
