Case 2: The Ultracapacitors Cells Are Connected into Two
Parallel Circuits. In this case, the ten cells of this module are divided into two
parallel circuits and deliver the energy to the load through the boost and the inductor.

parallel circuit.
The presence of an ideal
parallel circuit, tuned at the fundamental frequency, leads to a sinusoidal collector voltage giving a sinusoidal current flowing into the load resistor R, while all harmonic current components are flowing through this
parallel circuit having an infinite impedance at the fundamental and zero impedance at all harmonics.
When C and R are calculated from an equivalent series circuit of C and R, the value of R is almost the same obtained by
parallel circuit, but the value of R is around [10.sup.-6]F (Farads), which is far different from the observed value.
In view of the actual shunting route of lightning current, the sliding contact site is modeled as a simple
parallel circuit, as shown in Figure 3.
[Z.sub.1] is a RC
parallel circuit with resistance [R.sub.1] = 30[ohm] and capacitor [C.sub.1] = 5pF, [Z.sub.2] is a diode.
For example, WLEDs can be configured in series or
parallel circuit configurations depending on the type of display.
This, Bigoney said, allows the two-speed hydraulic motors to run in a
parallel circuit and provides three-speed selection by varying motor displacement independently while maintaining traction to prevent spinout or excessive braking on one wheel.
Basically, it can be considered as four independent hydraulic motors in a
parallel circuit connected to a common shaft, according to the company.
An advantage of the series feedback design is the relative ease of coupling to a single line compared to the
parallel circuit's requirement for coupling to two lines.
