Electricity and Magnetism

Front

What is electricity?

Back

Electricity is the flow of electric charge, typically through a conductor, and is used to power devices and systems.

What is a circuit?

Back

A circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, components are connected end-to-end, so the current is the same through all components. In a parallel circuit, components are connected across the same voltage source, allowing multiple paths for current.

What is an electromagnet?

Back

An electromagnet is a type of magnet that is created by electric current flowing through a coil of wire, which generates a magnetic field.

How do objects become positively charged?

Back

Objects become positively charged when they lose electrons.

What is the role of a resistor in a circuit?

Back

A resistor limits the flow of electric current in a circuit, protecting components from damage.

Front

What is the unit of electric current?

Back

The unit of electric current is the Ampere (A).

Front

What is voltage?

Back

Voltage is the electric potential difference between two points in a circuit, measured in Volts (V).
