What is the EMF Calculator?

The EMF Calculator helps students, engineers, and physics enthusiasts determine the electromotive force (EMF) of a circuit. By entering the work done on the charges and the total charge, the tool calculates the EMF, ensuring accurate results for experiments, homework, or practical applications. This eliminates manual calculation errors and provides a clear understanding of how electrical energy is generated per unit charge.

How to Use:

1. Enter Work Done (W, joules): Input the total work done on the charges in joules.
2. Enter Charge (Q, coulombs): Input the total charge in coulombs.
3. Click “Calculate”: The tool computes the EMF using the formula EMF=WQ\text{EMF} = \frac{W}{Q}EMF=QW​.
4. Review Result: The output displays the calculated EMF in volts (V) and ensures the entered values are valid and positive for accurate computation.
