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 | цена = E × Оценете
6 Calculation Types
Мощност
P = V × I, P = V² / R, P = I² × R
Напрежение
V = P / I, V = I × R, V = √(P × R)
Текущ
I = P / V, I = V / R, I = √(P / R)
Съпротива
R = V / I, R = V² / P, R = P / I²
енергия
E = P × t (поддържа секунди, минути, часове, дни)
цена
Cost = Energy × Rate per kWh
