Current Calculator Online

The current calculation formula is derived from Ohm’s law. Current is defined as the flow of electrons in an electrical circuit. The flow of electrons occurs due to potential differences. Current is also known as the rate of change of charge over time. Current is represented by I and the SI unit of current is Ampere.

Current calculation formula

We can calculate it using the current formula.

I = V/R I = 300/20 I = 15

I: Represents current in amperes.
V: Represents Volt, which is the potential difference.
R: Resistance in Ohm(Ω).

Example application: In an electrical circuit, potential difference and resistance are given as 300V and 20Ω respectively. Find the current flowing in the circuit using the current formula.

V = 300V R = 20Ω
