Voltage & Current Tools
Analyze voltage dividers, current dividers, and RMS values for AC/DC circuits. Essential tools for circuit design, signal processing, and determining peak vs. RMS voltage relationships.
Voltage Divider
Calculate the output voltage of a resistive divider circuit. Useful for scaling down voltages for sensor inputs and establishing reference levels in analog circuits.
Current Divider
Determine how total current splits between parallel branches in a circuit. Essential for analyzing parallel resistor networks and current distribution.
RMS to Peak Voltage
Convert RMS voltage to Peak and Peak-to-Peak values for sinusoidal waveforms. Critical for AC circuit analysis and understanding insulation requirements.
dBm to Watts
Convert RF signal power from decibel-milliwatts (dBm) to Watts. Essential for radio frequency engineering, Wi-Fi signal analysis, and telecommunications.
Watts to dBm
Convert electrical power in Watts to dBm. A standard calculation for expressing power levels in audio equipment, RF transmitters, and fiber optics.
Zener Diode Resistor
Calculate the required series resistor for a Zener diode voltage regulator. Protects your diode while maintaining a stable output voltage under load.
