Electric current is caused by moving electric charges. The effects of charge and electric fields can be investigated by looking at the forces they exert on conductors and insulators.
What is the overall electric charge of an atom?
How do like charges behave?
They repel one another
They attract one another
They have no effect on each other
In an electric field, what will a charged object experience?
What is the correct term for a build-up of charge on an insulating object?
A student rubs a balloon on their hair. Which particle moves from the hair to the balloon?
Which way should the arrows point on an electric field line?
From negative to positive
From positive to negative
There is no preferred direction
What is the definition of electric current?
Current is the rate of flow of charged particles
Current is how many charged particles there are
Current is the rate of flow of all particles
What is the formula for charge flow?
Charge flow (C) = current (A) × time (s)
Charge flow (C) = current (A) ÷ time (s)
Charge flow (C) = time (s) ÷ current (A)
When 10 C of charge flows for 0.01 s, what is the current?
What is the charge flow when a 5 mA torch is left on for 15 minutes?
