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.
V=IR
Where:
V=Voltage(V)I=Current(A)R=Resistance(Ω)
