Electrical Equations Calculator

The Electrical Equations Calculator available online will allow you calculate electrical components operational parameters to achieve circuits’ expected performances. An extensive set of equations is available at your fingertips to size any component available in the Main Electrical Library. Examples are shown below.

To name a few:

• Wire: Calculate wire length and power loss.
• DC generator:Size the electric output power and output voltage, armature current and parallel field current, as well as efficiency.
• 1-phase AC generator: Calculate slip and electric output power as well as efficiency.
• 3-phase (star and delta): Determine power factor, active power, reactive power and apparent power, and single-phase resistive loads, capacitor banks and inductive loads (R, C, R-L).
• Heating element: Evaluate resistance.
• Field effect transistor: Calculate channel length modulation parameter on P-Channel and N-Channel Junction Field Effect Transistor (JFET) and determine transconductance parameter and threshold voltage on P-Channel Insulated Gate Field Effect Transistor (MOSFET).
• Junction: Get early voltage, base current, saturation current of the emitter junction, saturation current of the collector junction, forward gain and reverse gain on the Bipolar Junction Transistor (BJT).
