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 | 비용 = E × 비율
6 Calculation Types
힘
P = V × I, P = V² / R, P = I² × R
전압
V = P / I, V = I × R, V = √(P × R)
현재의
나는 = P / V, I = V / R, I = √(P / R)
저항
R = V / I, R = V² / P, R = P / I²
에너지
E = P × t(초, 분, 시간, 일 지원)
비용
Cost = Energy × Rate per kWh
