Electricity and Magnetism

Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects, often caused by friction, which can result in sparks or shocks.

Front

What is the principle of charge transfer by friction?

Back

When two different materials are rubbed together, electrons can be transferred from one material to another, resulting in one object becoming positively charged and the other negatively charged.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which the components are connected end-to-end, so that the current flows through each component in turn.

Front

How many paths can charge flow in a series circuit?

Back

In a series circuit, there is only one path for charge to flow.

Front

What happens to the brightness of lights in a circuit when more batteries are added?

Back

Adding more batteries in a circuit increases the voltage, which makes the lights brighter.

Front

What does F_e represent in physics?

Back

F_e represents the electrostatic force, which is the force between charged objects.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electric charge to flow easily (e.g., metals), while insulators resist the flow of electric charge (e.g., rubber, glass).

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): V = I * R.

Front

What is the role of a switch in an electrical circuit?

Back

A switch is a device that can open or close a circuit, allowing or stopping the flow of electric current.

Front

What is an electric field?

Back

An electric field is a region around a charged object where other charged objects experience a force.
