Average Load Current of TRIAC Solution

Follow our step by step solution on how to calculate Average Load Current of TRIAC?

FIRST Step Consider the formula

I avg(triac) = \frac{2 \cdot \sqrt{2} \cdot I rms(triac)}{π}

Next Step Substitute values of Variables

∴

I avg(triac) = \frac{2 \cdot \sqrt{2} \cdot 0.09mA}{π}

Next Step Substitute values of Constants

∴

I avg(triac) = \frac{2 \cdot \sqrt{2} \cdot 0.09mA}{3.1416}

Next Step Convert Units

∴

I avg(triac) = \frac{2 \cdot \sqrt{2} \cdot 9E-5A}{3.1416}

Next Step Prepare to Evaluate

∴

I avg(triac) = \frac{2 \cdot \sqrt{2} \cdot 9E-5}{3.1416}

Next Step Evaluate

∴

I avg(triac) = 8.10284684541396E-05A

Next Step Convert to Output's Unit

∴

I avg(triac) = 0.0810284684541396mA

LAST Step Rounding Answer

∴

I avg(triac) = 0.081mA

How to Evaluate Average Load Current of TRIAC?

Average Load Current of TRIAC evaluator uses Average Load Current TRIAC = (2*sqrt(2)*RMS Current TRIAC)/pi to evaluate the Average Load Current TRIAC, Average Load Current of TRIAC is the average value of the current that flows through the load during the time that the TRIAC is conducting. It is calculated by taking the integral of the current waveform over the conduction period and dividing by the conduction period. The RMS value of the AC voltage is the voltage that would produce the same heating effect as the actual AC voltage waveform. The trigger angle is the angle at which the TRIAC is triggered relative to the peak of the AC voltage waveform. The load impedance is the resistance, inductance, and capacitance of the load. Average Load Current TRIAC is denoted by I_avg(triac) symbol.
