Applied Voltage Calculator
Calculate applied voltage in AC/DC circuits easily using formulas. Quick tool with tables, formulas, and examples for engineers and students.
applied potential difference calculator
In DC circuits, Ohm's Law (V = I × R) can be used to determine applied voltage and impedance in AC circuits (V = I × Z).
Formula & Table Summary:
| Formula | Description |
|---|---|
| V = I × R | Applied voltage in DC |
| V = I × Z | Applied voltage in AC |
applied voltage calculator
The Applied Voltage Calculator is useful in determining the actual voltage that is applied in a circuit. Use V = I × R for DC or V = I × Z for AC. Convenient in designing and troubleshooting.

Frequently Asked Questions - Applied Voltage Calculator:
What is applied voltage?
Applied voltage is the voltage supplied to a circuit or component by a source.
How do you calculate applied voltage in DC?
Use V = I × R, where I is current and R is resistance.
How do you calculate applied voltage in AC?
Use V = I × Z, where Z is impedance.
Is applied voltage the same as source voltage?
Yes, in ideal conditions, but real systems may include drops or losses.
What is the unit of applied voltage?
Applied voltage is measured in volts (V).
Why is applied voltage important?
It determines how much electrical energy is delivered to a circuit or device.
How can I measure applied voltage?
Use a voltmeter across the circuit input terminals.
Can applied voltage be higher than rated voltage?
Yes, but it may damage equipment if it exceeds safe limits.
What happens if applied voltage is too low?
The circuit may not work correctly, and devices may underperform.
Is applied voltage affected by load?
Yes, in real systems load can cause drops, making applied voltage lower than source voltage.
