There are two 100μF capacitors. One is charged to an initial voltage of 50V and the other to an initial voltage of 100V. They are then placed in series with the positive terminal of the first connected to the negative terminal of the second. The question isto find the equivalent capacitance and the initial voltage. Then find the energy stored in the two capacitors and the equivalent capacitor, respectively. Note: The latter will be smaller than the former.

Calculate the magnitude of the characteristic impedance and the propagation constant for a coaxial line at 2 GHz. Assume that b = 3 cm, a = 0.5 cm, and e = e0 (2.56 - j0.005).
A single phase transformer rated 1.2kV/120V, 7.2kVA hasprimary-referred parameters Req= r1+ a r2= 1Ω andXeq = x1+ a2 x2 =4Ω when neglecting exciting current. At rated voltage itscore loss may be assumed to be 40W for all the load curent.
Obtain the discrete-time (DT) or sampled signals x[n] = x(nTs) and h[n] = h(nTs) by discretizing the CT signals x(t) and h(t), respectively, using a sampling period of Ts = 0.01 s. This value ensures that the two CT signals can be fully recovered,..
Construct an inverting Dc integrator circuit using a jumperwire to act as the switch across the feedback capacitor. Notice that the input voltage is 0 V, so the output voltage shouldnot change, even after the switch is opened.
Provide an output V to indicate that at least one of theinputs is present. The input with the highest subscript number has the highest priority. What will be the value of the four outputs if inputs D2 and D6 are 1 at the same time
Two batteries with 1.8 voltage and 10.5 Ohm internal resistance each are connected in series. This battery pack is used to boot a small electric motor with 275 Ohm resistance. Find the power delivered to the motor.

A transmitter transmits an AM sinal with a carrier frequncy of 1530kHz. When an inexpensive radio receiver (which has a poor selectivity in its RF-stage bandpass filter) is tuned to 1530kHz, the signal is heard loud and clear.
In the 3-Op Amp Instrumentation amplifier, all the resistor values are the same with the exception of RG which determines the gain. Is it possible to have additional gain at the output Op Amp of Rf/Rin
