Electric current Definition of electric current Measuring electric current (the ammeter)
Measuring electric current To measure the electric current flowing in a circuit we use an Ammeter. But what is electric current?
Q is the amount of charge • I is the current • t is the time taken to measure Q So ELECTRIC CURRENT is the amount of charge passing through a wire in the unit of time Now, from the current equation write the equations to find the time and the charge!
How does an Ammeter work? It is just like a little person counting how many charges (electrons) pass through a section of a wire in a certain time. Oh dear! I think there were 100000 electrons this time!
