Static Electricity and Friction | GCSE Physics Practice

Static electricity is the build-up of electric charge on the surface of an insulator.

Why does hair stand up after rubbing it with a balloon?

What is Static Electricity and Friction | Practice?

"An imbalance of electric charges within or on the surface of a material, created by friction between insulators."

Question 1

What is the unit of electrical resistance?

Question 2

Misconception: When a circuit is closed, the 'spent' current returns to the battery.

Question 3

Calculate the charge flow if a 3A current flows for 10 seconds.

Question 4

Current is the rate of flow of ____.

Friction between two insulators transfers electrons from one to the other.

The material that gains electrons becomes negatively charged.

The material that loses electrons becomes positively charged.

Like charges repel; opposite charges attract.

Exam Tip

Safety Fact: Sparks occur when the potential difference between the object and the earth is high enough to ionise the air.

The fastest way to improve your grade is to practise exam-style questions, identify your gaps, and focus only on what you don't know.
