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, theÂ **quantity of chargeÂ **isÂ **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, theÂ **timeÂ **isÂ **3 secs.**
