Calculate relationship between voltage, current, resistance and power in electrical circuits.
Calculate Voltage, Current, Resistance, or Power. Enter any two.
Our Ohm's Law Calculator is a versatile tool for electrical engineering and electronics. Enter any two values among voltage, current, resistance, or power to instantly calculate the others using standard electrical formulas.
V = I × ROhm's Law states that the voltage (V) across a conductor is proportional to the current (I) flowing through it and the resistance (R) of the conductor.
Voltage (V) is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop.
Electric power (P) in Watts is calculated by multiplying Voltage (V) and Current (I). It represents the rate at which electrical energy is transferred.
Yes, for most conductors, resistance increases as temperature rises because higher thermal energy causes atoms to vibrate more, hindering electron flow.
