What is This Calculator?

This electricity calculator uses Ohm's law and power formulas to calculate power, voltage, current, resistance, energy consumption, and electricity cost. It is designed for electrical engineers, students, electricians, and anyone working with electrical circuits.

Ohm's Law & Power Formulas

V = I × R  |  P = V × I  |  P = V² / R  |  P = I² × R

E = P × t  |  Κόστος = E × Τιμή

6 Calculation Types

Εξουσία

P = V × I, P = V² / R, P = I² × R

Δυναμικό

V = P / I, V = I × R, V = √(P × R)

Ρεύμα

I = P / V, I = V / R, I = √(P / R)

Αντίσταση

R = V / I, R = V² / P, R = P / I²

Ενέργεια

E = P × t (υποστηρίζει δευτερόλεπτα, λεπτά, ώρες, ημέρες)

Κόστος

Cost = Energy × Rate per kWh
