Ohm's law online calculator

***** Amperage *****
The current in the conductor is directly proportional to the voltage and inversely proportional to the resistance.

Indicate voltage (U):
Volt
Indicate resistance (R):
Ohm
Result:
Amperage (I) Ampere ***** Voltage *****
The voltage drop in the conductor section is equal to the product of the current in the conductor by the resistance of this section.

Indicate current strength (I):
Ampere
Indicate resistance (R):
Ohm
Result:
Voltage (U) Volt ***** Electrical resistance *****
Electrical resistance determines the strength of the current flowing through the circuit at a given voltage.
