Electricity

Front

What is static electricity?

Back

Static electricity is a build-up of electric charge, typically involving protons or electrons.

Front

What is resistance in an electric circuit?

Back

Resistance is the slowing down of an electric current, which opposes the flow of electrons.

Front

How do electrons behave in a current?

Back

Electrons repel each other due to their like charges.

Front

What is a conductor?

Back

A conductor is a material that allows the flow of electrons.

Front

What is an electric field?

Back

An electric field is an invisible force field created by the flow of electrons through a conductor.

Front

What is the difference between static and current electricity?

Back

Static electricity is a stationary charge, while current electricity is the flow of electric charge.

Front

What materials are typically good conductors?

Back

Metals such as copper, aluminum, and silver are typically good conductors.

Front

What is the unit of resistance?

Back

The unit of resistance is the ohm (Ω).

Front

What factors affect resistance in a conductor?

Back

Resistance in a conductor is affected by its length, cross-sectional area, temperature, and material.

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.
