Notes

  • Results are approximate and should be verified for critical applications
  • Input values should be within reasonable engineering ranges

Additional Formulas

Power Dissipated by a Resistor P=UI=RI2=U2RP = UI = RI^2 = \frac{U^2}{R} Where:

  • P = Power (W)
  • U = Voltage (V)
  • I = Current (A)
  • R = Resistance (Ω)

Resistor Specifications

Standard resistors are available in a wide range of specifications.

Key Concepts

Thévenin's Theorem

Any two-terminal network consisting of resistors and voltage sources can be replaced by an equivalent circuit consisting of a single voltage source (V_th) in series with a single resistance (R_th). This simplifies the analysis of complex circuits, particularly when calculating the current through or voltage across a specific load component.
