Depending on the size of a compensation unit, it is assembled with capacitors of equal size (in bigger units) or of different size. A unit with a total reactive power of, for example,300 kvarconsists of six power capacitors, of 50 kvar each. How to calculate number of steps & reactive ...
Re: how to calculate capacitor values 12/02/20098:53 AM Calculation of Required Power Factor The reactive power which is necessary to achieve a desired power factor is calculated by the following formula: QC= P • F QC- Reactive power of the required correcting capacitor P - Active power ...
In addition, the ADC conversion results may not be accurate, except if the external capacitor (CAIN + Cp) is fully charged to the level of the input voltage. The greater value of (CAIN + Cp), the more limited the source frequency. The external capacitance at the source and the ...

When a resistor is embedded in a PCB, the surrounding copper layers and prepreg material help dissipate heat, allowing it to handle higher power more efficiently. Consider these guidelines to ensure power integrity: Calculate the power dissipation using the formulaP=I2R. ...
Q1:when calculate the max voltage drop of bootstrap capacitor,I do not understand the last item of the formula:Vcesat.Why subtract Vcesat??? Q2:The article shows how to calculate the value of bootstrap resistor,but how to know the charge current?The charge current ...
For some antenna shapes, Section 3.1, Section 3.2, and Section 3.3 give useful formulas to calculate the self-inductance Lant, even if the stray capacitance of the antenna is not estimated. Section 3.4 presents a calculation tool called Antenna Design, which is a part of the eDesignsuite,...
Signal from resistor R3 travels down the wire to tube V1A's grid (pin 2) then out the plate to coupling capacitor C1. Tube V1 is split into two identical halves, A & B.After going through grid stopper resistor R3 the audio signal flows down the wire to the preamp tube's control ...
Step 2:Determine which form of the energy equation to use based on the know values. Since we are given the capacitance and the voltage, we will useEcap=CV22 Step 3:Calculate the Energy stored in the capacitor. Ecap=(2.0μF)(50V)22=(2.0x10−6F)(50V)22=0.0025J ...
