Electric Current Formula And Sums

Electric Current Formula :

Electric current formula is electric current charge I(c) in coulomb is equal to the product of the current flows the negative terminal to the positive terminal of the cell Q(A) in Ampere and divided by the time travelled t(s) in second. Hence the Electric current formula can be written as

I(c)=Q(A)/t(s)

Example:1

Calculate the amount of electric charge that flows through the circuit? In a current of 0.85A is drawn by the filament of an electric bulb for 10minutes .

Answer:

Given I=0.85A t=10 minutes =600s

We know Q=I*t=0.85*600

Therefore Q=510 C

Example:2

Calculate the amount of electric charge that flows through the circuit? In aA current of 2.50 A is drawn by the filament of an electric bulb for 10minutes

Answer:

Given I=2.50 A, t=10 minutes =600s

We know Q=I*t=2.50*600

Therefore Q=1500 C
