Welcome! This page will use Ohm's Law to calculate voltage in a circuit given current and resistance.
Our ohms to volts calculator can be used to find component-specific voltages or total voltage in a circuit assuming a DC source.
Ohm's law is the foundation of electrical analysis and, thus, incredibly useful for circuit design.

Explanation
Ohm's law describes the relationship between voltage, current and resistance. A larger current and resistance give rise to a larger voltage. However, a larger resistance reduces the total current if the voltage is constant.

👉 Important information
Voltage can also be referred to as electromotive force (E), Voltage drop, or EMF. These terms can be confusing when performing calculations.
To find the voltage drop across a specific component, you must use its particular resistance value.
Be careful when you are using series and parallel circuits!
❗This equation will not work on AC components (inductors, capacitors) and non-linear components such as transistors and MOSFETS.
