Initial Current Calculator

Formula

To calculate the Initial Current (Ii):

$Ii = \frac{\text{EMF}}{R}$

Where:

$Ii$ is the Initial Current (amps)
$\text{EMF}$ is the strength of the emf (volts)
$R$ is the total resistance (ohms)

What is Initial Current?

Initial Current (Ii) is the current that flows through a circuit immediately after a voltage is applied. It is calculated by dividing the strength of the electromotive force (EMF) by the total resistance in the circuit.

Example Calculation 1

Let's assume the following values:

EMF = 12 volts
Resistance = 4 ohms

Using the formula:

$Ii = \frac{12}{4} = 3 \text{ amps}$

The Initial Current is 3 amps.

Example Calculation 2

Let's assume the following values:

EMF = 24 volts
Resistance = 6 ohms

Using the formula:

$Ii = \frac{24}{6} = 4 \text{ amps}$

The Initial Current is 4 amps.
