Calculate the resonant frequency of an LC circuit — essential for filters, oscillators, and tuning circuits. "The natural frequency at which an LC circuit stores and exchanges energy between magnetic and electric fields." Key Formula: Resonant Frequency f0 = 1 / (2 π √LC) Where: f0: Resonant frequen
Calculate output voltage using the voltage divider rule — essential for electronics design. "A circuit that reduces voltage by dividing it across two resistors in series." Key Principle: Voltage Divider Rule Vout = Vin * R2 / (R1 + R2) Where: Vin: Input voltage (V) Vout: Output voltage (V) R1, R2: R
Calculate output current in parallel circuits using the current divider rule. "A circuit that produces an output current proportional to the input, based on resistor ratios." Key Principle: Current Divider Rule I₁ = I * R₂ / (R₁ + R₂) and I₂ = I * R₁ / (R₁ + R₂) Where: I: Total input current (A) I1:
Calculate inductive and capacitive reactance in AC circuits. "The opposition caused by inductance or capacitance to alternating current." Types of Reactance Inductive Reactance (XL): Opposition from inductors to AC current Capacitive Reactance (XC): Opposition from capacitors to AC current Key Formu
Power factor correction (PFC) is a technique that improves the efficiency of an electrical system by adding capacitors to offset the reactive power generated by inductive loads (e.g., motors, transformers). This reduces current draw, minimizes energy losses, and lowers utility bills. This tool calcu
What is Impedance? Impedance is the total opposition a circuit offers to the flow of alternating current (AC). It combines resistance (R) and reactance (X), and is measured in ohms (Ω). “The opposition of a circuit to the passage of an alternating electric current.” Key Parameters Resistance (R) The
In certain power networks, a significant difference may exist between the rated voltage and the service voltage. For example, a capacitor rated at 400 V may be used in a 380 V system. In such cases, the actual reactive power output of the capacitor varies with voltage and frequency. This tool calcul
This tool calculates the grounding resistance of an earthing system based on soil resistivity, electrode type, and geometric parameters. It helps verify compliance with IEC 60364-4-41 for coordination between earth electrodes and residual current devices (RCBOs). The calculated resistance is compare
