Compute the time constant of the circuit below in units of ms (Do not enter units in the solution box, only the value) Switch

2. A bank of nickel-cadmium cells is used as the emergency lighting supply for a hospital. There are 100 cells connected in series and each has an A-hr rating of 120 A-hr. The bank has to be replaced, and the manufacturer is no longer supplying nickel-cadmium cells. It is decided to replace the cells with lead-acid cells. How many lead-acid cells will be required if each has an A-hr rating of 60 A-hr, and how should they be connected?

Cyclic Voltammetry and Charge-discharge The given figure is the Galvanostatic Charge-discharge curves of a supercapacitor made with MnO2 coated on a CNT electrode.  Potential is measured with respect to time by applying different current densities. Based on the plot, answer the following questions   4. Is it possible to estimate maximum power of the device with this charge-discharge curve? If possible, explain how you would do it. (calculation is not necessary)

TOPIC: STABILITY   Subject to a step input, the voltage drop across the resistor took 696.3103us to reach 13% of its steady value from rest. Determine the time (ms) needed to reach 90% of its steady value from 10% Determine the time (ms) needed to reach 80% of its steady value from 20%

A series circuit contains a resistor and a capacitor as shown in Figure 1. Suppose the capacitor in the circuit initially has zero charge and that there is no initial current. When the switch is at position B, the 10 Volt power supply energized the capacitor through the 250 № resistor, until fully charged, thus producing an output voltage E. At time t=2 seconds, the switch is thrown from position B to A, held there for 1 second, then switch back to B. (c) 10 V (d) 250 92 B Figure 1 10.³F (a) Write the differential equation for the charge q(t) of the circuit. (b) Given the forcing function is zero until t = 2, then has value 10 volts until t = 3, then is zero again, express E(t) in terms of unit step function and sketch the function E(t). Egut Find the charge on the capacitor using part (a) and (b). Use the Laplace transform method. What is the output voltage E(t) on the capacitor?
