Calculators

Calculates the Root Mean Square (RMS) value of an AC voltage, representing its effective DC equivalent.

Calculates the output voltage from a simple circuit that divides a source voltage across two resistors.

Analyzes circuits with resistors, inductors, and capacitors, calculating impedance and resonant frequency.

Analyzes circuits containing resistors and capacitors, calculating time constants and charge/discharge behavior.

Calculates the electrostatic force between two point charges.

Calculates the electric field strength created by a point charge.

Calculates the electric potential (voltage) at a point due to one or more point charges or in a uniform electric field.

Calculates voltage, current, or resistance in an electrical circuit using Ohm's Law (V=IR).

Calculates the capacitance of various capacitor configurations.

Calculates electrical power using voltage, current, and resistance, based on the formulas P=VI, P=I²R, and P=V²/R.
