To calculate the quantity of charge, two essential parameters are needed and these parameters are current (I)Â and time (T).
The formula for calculating the quantity of charge:
Q = It
Where;
Q = Quantity of charge
I = Current
T = Time
Let’s solve an example;
Find the quantity of charge with a current of 24 and time of 12.
This implies that;
I = Current = 24
T = Time = 12
So, Q = It
Q = 24 x 12
Q = 288
Therefore, the quantity of charge is 288 Coulombs (C).
Calculating the Current (I) using the Quantity of Charge and Time
I = Q / t
Where;
I = Current
Q = Quantity of charge
T = Time
Let’s solve an example;
Given that the quantity of charge is 240 with a time of 14. Find the Current?
This implies that;
Q = Quantity of charge = 240
T = Time = 14
That is, I = Q / t
I = 240 / 14
I = 17.14
Therefore, the current is 17.14 ampere.

Calculating the Time (t) when the Quantity of Charge and Current is Given
t = Q / I
Where;
I = Current
Q = Quantity of charge
T = Time
Let’s solve an example;
Find the time of a quantity of charge of 90 with a current of 30.
This implies that;
I = Current = 30
Q = Quantity of charge = 90
Then, t = Q / I
t = 90 / 30
t = 3
Therefore, the time is 3 secs.
