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  |  Kosten = E × Tarief

6 Calculation Types

Stroom

P = V × I, P = V² / R, P = I² × R

Spanning

V = P / I, V = I × R, V = √(P × R)

Huidig

ik = P / V, ik = V / R, ik = √(P / R)

Weerstand

R = V / I, R = V² / P, R = P / I²

Energie

E = P × t (ondersteunt seconden, minuten, uren, dagen)

Kosten

Cost = Energy × Rate per kWh

Hoe te gebruiken

  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.
