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).**

**Calculating the Time (t) of a charge using the Quantity of the charge (Q) and the Current (I).**

t = ^{Q} / _{I}

Where;

t = Time

Q = Quantity of charge

I = Current

Let’s solve an example;

Find the time of a charge when the quantity of the charge is 250 C with a current of 18 A.

This implies that;

Q = Quantity of charge = 250

I = Current = 18

t = ^{Q} / _{I}

t = ^{200} / _{18}

t = 11.1

Therefore, the **time** is **11.1 secs.**
