What is the difference between static electricity and current electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects, while current electricity is the flow of electric charge through a conductor.

What is the role of a compass in understanding magnetism?

Back

A compass uses a magnetic needle that aligns with the Earth's magnetic field, helping to indicate direction.

Front

What is the principle of electromagnetic induction?

Back

Electromagnetic induction is the process of generating electric current in a conductor by changing the magnetic field around it.

What is the relationship between voltage, current, and resistance?

Back

This relationship is described by Ohm's Law: Voltage (V) = Current (I) x Resistance (R).
