The calculation of the current in an electric circuit online calculator


Our online calculator will help you in calculating the current in an electric circuit.
The current in an electric circuit is the amount of electricity that passes through the cross section of the conductor in one second.
If through the cross section of the conductor passes one Coulomb of electricity per second, it is the strength of the current in the conductor is one ampere.
Calculate the current consumption of the electric device, can be knowing the supply voltage and its power.
You can also specify (supply) – a one-or two-phase, and (the nature of the load), which can be active or reactive.
The calculation of the current in an electric circuit necessary for example to know what section of wire to choose in the process of wiring, as well as to calculate the fuse rating to determine the current consumption of any electrical equipment.

Indicate the type of mains supply:

Indicate the nature of the load:

Indicate load power (W):

Indicate the voltage in the network (V):


Current in the circuit (A):
