The image above represents the quantity of charge.
To compute the quantity of charge, two essential parameters are needed and the parameters are current (I) 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 when the current (I) is 24 amp with a time of 8 secs.
This implies that;
I = Current = 24 amp
t = Time = 8 secs
Q = It
Q = 24 x 8
Q = 192
Therefore, the quantity of charge is 192 coulombs (C).
Calculating the Current (I) of a charge using the Quantity of Charge (Q) and the time (t).
I = Q / t
Where;
I = Current
Q = Quantity of the charge
t = Time
Let’s solve an example;
Find the current of a charge with the quantity of the charge as 150 coulombs (C) and time as 15 secs.
This implies that;
Q = Quantity of the charge = 150 C
t = Time = 15 secs
I = Q / t
I = 150 / 15
I = 10
Therefore. the current is 10 Ampere (A).
