What is meant by parasitic resistance?
In electrical networks, a parasitic element is a circuit element (resistance, inductance or capacitance) that is possessed by an electrical component but which it is not desirable for it to have for its intended purpose.
What is meant by unloaded Q of tank circuit?
X is the capacitive reactance, and R is the series resistance. Since this Q refers only to the capacitor itself, in isolation from the rest of the circuit, it is called unloaded Q or QU. The higher the unloaded Q, the lower the loss. Notice that the Q decreases with frequency. The unloaded Q of an inductor is given by.
How is trace inductance measured?
Calculate the PCB trace inductance, or “L,” using the formula L = Zo * DLY. Using the example numbers: L = 20 x 10^-3 * 12 x 10^-12 = 240 x 10^-15 henries or 0.24 pH, where pH is units of picohenries. Traces on PCBs are small and therefore have small inductance levels.
What causes parasitic resistance?
the strength of the infected animal’s immune system; the practices used to treat the parasite; the properties of the particular antiparasitic drug used; and. certain livestock management practices.
What are the two types of parasitic resistances and their cause?
The most common parasitic resistances are series resistance and shunt resistance. The inclusion of the series and shunt resistance on the solar cell model is shown in the figure below. Parasitic series and shunt resistances in a solar cell circuit.
What is Q-factor in circuit?
Q factor (also known as Quality Factor or Q-factor) is defined as a dimensionless parameter that describes the underdamped condition of an oscillator or resonator. The quality factor measures the performance of a coil, a capacitor, or an inductor in terms of its losses and resonator bandwidth.
How to calculate total resistance in a series circuit?
Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms (Ω) Formula to calculate resistance in a series circuit. Calculate the total resistance of the following resistors in a series. Therefore, the total resistance is 39 ohms.
How to calculate the resonance of a tank circuit?
Calculating the Resonant Frequency of a Tank Circuit. f r = 1 2π√LC f r = 1 2 π L C. Where: f r f r = resonant frequency. L L = circuit inductance. C C = circuit capacitance.
What kind of circuit is a tank circuit?
What is a Tank Circuit? A tank circuit is a parallel combination of a capacitor and inductor and is the most common “resonant” circuit — a circuit that absorbs maximum power at a particular frequency (called the resonant frequency).
