Electrical current transfers energy around circuits. There are two types of current: direct and alternating.
What are the particles responsible for transferring electrical energy from a cell, through conducting wires in an electric circuit?
What is the relative charge of an electron?
What is the unit of electric charge?
What is the unit of electric current?
Which equation correctly links the quantity of charge Q, Current I and time t.?
Q = I x t
Q = I ÷ t
I = Q x t
A current of 2.5 A flows through a simple electrical circuit. How many coulombs of charge flow through a point in 2 minutes?
How much current flows when 50 C passes down a wire in 10 s?
What instrument is used to measure electric current?
A current meter
Where should an ammeter be connected in an electric circuit?
Before a component in the circuit but not after it
