Electric current strengt (i)

The amount of electric charge that flows in a conductor in each second is called electric current strength. It is also can define as a quotient between electric charge that flows through a conductor wire section and the time interval. Mathematically formulated as.

Example 2.1 In a conductor wire it flows a charge of 300 C for 1 minute. What is value of electric current strength that flows in the wire? Answer:

Where:

I= electric current (A)

Q= Charge (C)

T=time (s)

an instrument to measure the amount of electric current that passed through the circuit is called ammpermeter. And it must be arranged in series, so the electric current direcly pass through ampermeter.
