Question

The motor in a hairdryer is attached to a 3V battery. A current of 0.8A flows through the motor for 3 minutes. Calculate the total charge in this time.

Answer 1

The total charge in this time is equal to 144 Coulomb.

Given the following data:

• Voltage = 3 Volts

• Current = 0.8 Amperes

• Time = 3 minutes.

To calculate the total charge in this time:

First of all, we would convert the value of time in minutes to seconds.

Conversion:

1 minute = 60 seconds

3 minutes = 180 seconds

Formula for quantity of charge.

Mathematically, the quantity of charge is given by this formula:

$Q=It$

Where:

• Q is the quantity of charge.

• I is the current.

• t is the time measured in seconds.

Substituting the given parameters into the formula, we have;

$Q = 0.8 \times 180$

Quantity of charge, Q = 144 Coulomb.
