Circuit Ro Figure 21.50 A bleeder resistor R discharges the capacitor in this electronic device once it is switched off.

A voltage Δ V n resistors, each of resistance R. The circuit components are reconnected in a parallel configuration, and voltage Δ V is again applied. Show that the power consumed by the series configuration is 1/ n2 times the power consumed by the parallel configuration.

The figure below shows how a bleeder resistor (R = 246 kΩ) is used to discharge a capacitor (C = 77.7 µF) after an electronic device is shut off, allowing a person to work on the electronics with less risk of shock. (a) What is the time constant? (in s)(b) How long will it take to reduce the voltage on the capacitor to 0.100% of its full value once discharge begins? (in s)(c) If the capacitor is charged to a voltage V0 through a 123 Ω resistance, calculate the time it takes to rise to 0.865V0 (this is about two time constants).(in s)

You have a circuit that has two capacitors that are in parallel to each otherin a circuit. The first capacitor is a parallel plate capacitor with a capacitance of 5.0pF and an area of 200 mm2. The second capacitor is also a plate capacitor with aseparation distance of 2 mm.(a) Draw a circuit showing just a battery and the two capacitors.(b) If the energy stored on the first capacitor is 10 µJ, what is the voltage drop acrossthat capacitor?(c) If the second capacitor can store twice as much energy as the first capacitor, whatis the area of the 2nd capacitor’s plates?(d) What is the distance between the plates for the first capacitor?

An electrical technician requires a capacitance of 2 µF in a circuit across a potential difference of 1 kV. A large number of 1 µF capacitors are available to him each of which can withstand a potential difference of not more than 400 V. Suggest a possible arrangement that requires the minimum number of capacitors.

Stuck and slightly confused on the calc based physics question attached.  output voltage (Vout) is measured across the resistor

What do you expect the resistance of a fully- discharged capacitor to be? Why? What do you expect the resistance of a fully-charged capacitor to be? Why?

In the circuit shown the capacitor starts discharged. The switch S is closed to theupper position at t = 0.(a) What is the voltage in the capacitor at t = 2 seconds?(b) How much time does it take the capacitor to reach 99% of its maximum voltage.

For a parallel circuit, the power storage voltage is 6 V.  The nominal resistance for R1 and R2 is 150 ohms and 220 ohms, respectively. If 1/Rt = R2 +R2/R1*R2, then Rt R1*R2/R2+R1 =1 From the attached, so as to understand conceptually, can you explain and describe from the nominal resistance for R1 and R2 given, the general nature of a parallel circuit in terms of the columns given specified in the variables and the relationship, such a V to V1 and V2; I to I1 and I2, then I1 +I2?
