Formula Used
Unit conversion: Current in amperes = entered value × input unit factor. Requested output = target amperes ÷ output unit factor.
Sine wave relationships: Peak = RMS × √2, Peak-to-Peak = 2 × Peak, Average Rectified = Peak × 2/π.
Square wave relationships: RMS = Peak, Peak-to-Peak = 2 × Peak, Average Rectified = Peak.
Triangle wave relationships: RMS = Peak ÷ √3, Peak-to-Peak = 2 × Peak, Average Rectified = Peak ÷ 2.
DC relationships: RMS = Peak = Average Rectified. Peak-to-Peak is zero for an ideal constant current.
Burden and energy formulas: Voltage = IRMS × R, Power = IRMS2 × R, Charge = IAVG × t, Energy = Power × t.

Frequently Asked Questions
1. What does this current converter calculate?
It converts current between electrical units and waveform forms. It also estimates burden voltage, power dissipation, charge flow, and energy when optional resistance and duration are provided.
2. Why do waveform selections matter?
RMS, peak, and average values depend on waveform shape. A sine wave and square wave with the same peak current do not have the same RMS current.
3. When should I use RMS current?
Use RMS current for heating, power, and resistor stress calculations. RMS reflects the equivalent DC current that produces the same thermal effect in a resistive load.
4. What is average rectified current?
Average rectified current is the average of the absolute waveform over time. It is common in rectifier analysis, analog meter scaling, and ripple-related electrical calculations.
5. Can I use this for current transformer burdens?
Yes. Enter the expected RMS current and burden resistance. The calculator will estimate the burden voltage and power, which helps during secondary loading checks.
6. Why is peak-to-peak unavailable for constant DC input?
Ideal constant DC does not swing between maximum and minimum values. Because it has no alternating excursion, peak-to-peak input is not physically meaningful here.
7. What units are supported?
The calculator supports kiloamperes, amperes, milliamperes, microamperes, and nanoamperes. All values are converted internally through amperes for consistent accuracy.
8. What is the charge flow result used for?
Charge flow shows how much electrical charge passes during the selected duration. It is useful in capacitor studies, pulse discussions, and measurement summaries.
