Insulation resistance is determined as per the following formula R=E/Iequiv - 0.5 r, where E - source voltage, Iequiv - equivalent current, r - resistance of resistors.;EFFECT: excluding measurement error from unbalance current in circuit of resistors.;3 dwg, 6 clROMANOV SERGEJ VALENTINOVICH...
The formula shown here should be familiar to you. It has the same form as the total resistance formula for series circuits. Just as resistances add in series (more series resistance makes the overall resistance to current increase), conductances add in parallel (more conductive branches makes th...

Thus, in low power applications, AC to DC rectifier circuits are still commonly used which sink large amounts of current from the AC mains when close to the peak, leading to the grid voltage waveform distortion. SUMMARY - Top of Page OF THE INVENTIONS Accordingly, the technical problem to...
In case of photodetectors, photocurrent can be estimated by the following formula [29,30]: (1)Iph=Ilight−Idark where, IPh denotes photocurrent; Ilight and Idark are current achieved from device under light and dark conditions, respectively. 1.2.2 Photoresponsivity (Rλ) Photoresponse is one...
The current is calculated from the average of a half-wave rectified sinusoidal waveform, hence the required value of the current limiting resistor.

types of current flow in a circuit. Indirect current(DC), the electric charge (current) only flows in one direction. Electric charge inalternating current(AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes ...
In addition, power electronic circuits are applied with control circuits to attain GMPP operation14,15. Many tracking approaches have been, recently, introduced to attain the optimal power of the PV system, which has drawn considerable interest from researchers16,17. Two MPPT categories are broadly...
Inductors found in high-frequency circuits are air-core solenoids with values in the milli-Henry (mH) range. As in the case of capacitance, assuming sinusoidal variations will quickly show the characteristics of inductance. If (as shown in Fig. 1.7a) a current source which produces a current...
