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 | Расходы = E × Ставка
6 Calculation Types
Власть
P = V × I, P = V² / R, P = I² × R
Напряжение
V = P/I, V = I × R, V = √(P × R)
Текущий
Я = П/В, Я = В/Р, Я = √(П/Р)
Сопротивление
R = В/I, R = V²/P, R = P/I²
Энергия
E = P × t (поддерживает секунды, минуты, часы, дни)
Расходы
Cost = Energy × Rate per kWh
