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  |  Kosta = E × Hastighet

6 Calculation Types

Driva

P = V × I, P = V² / R, P = I² × R

Spänning

V = P / I, V = I × R, V = √(P × R)

Nuvarande

I = P / V, I = V / R, I = √(P / R)

Motstånd

R = V/I, R = V²/P, R = P/I²

Energi

E = P × t (stöder sekunder, minuter, timmar, dagar)

Kosta

Cost = Energy × Rate per kWh

Hur man använder

  1. Select a calculation type (Power, Voltage, Current, Resistance, Energy, or Cost).
  2. Choose the formula method based on the values you know.
  3. Enter your values and select appropriate units.
  4. Click Calculate to get results with step-by-step solutions and charts.

Viktiga anmärkningar

  • All input values must be positive numbers.
  • Resistance and divisor values must be greater than zero.
  • Enhetskonverteringar hanteras automatiskt.
