A voltage source V(t)=100cos(6Π109t - 45(degrees))(V) is connected to a series RLC circuit. If R = 10MΩ, C = 100pF, and L = 1H, use phasor notation to find the following:
a.) i(t)
b.) Vc(t) (voltage across capacitor)
a) Design the doubler circuit shown in Figure 2, for which:D = d8 d4 d2 d1 and B = b8 b4 b2 b1 are each an 8421 BCD code digit. The circuit must implement the equation: 10C* + B = 2D + C
Each equation above describes a field that is distributed sinusoidally and whose amplitude varies sinusoidally with time (a pulsating field). Prove for the resultant magnetic flux density in the air gap (a) at any given t
determining whether the number divided evenly can be accomplished by determining if there is a remainder. Implement the program using a for loop for the calculations. Additional hint: a break in the loop can make the program simpler, though it is ..
A single phase transformer has the following rating: 120 kVA, 2000 V/100 V, 60 Hz with 1000 primary turns. Determine (A) the maximum flux. (B) given a maximum flux density of 0.25 T, the cross-sectional area of the core.
A silicon diode with a breakdown voltage of 2000V that is conducting a forward current of 2000A is turned off with a constant diR/dt=250 A/s. Roughly estimate the time required for the diode to turn off.
There are a number of factors and precautions that need to be considered when developing and introducing new technologies to the marketplace. This is especially the case when this could be a technology without a sustainable known history.
Design a digital circuit that can be attached to a school bill which can work automatically from 7:00 AM to 12:45 PM, and it has the following features: 1- Rings for 5 seconds. 2- Start ringing 7:00 AM to announce for the field gathering. 3- Rings 7:..
An abrupt silicon pn junction at zero bias has dopant concentrations of Na = 1017/cm3 and Nd = 5 x 1015 cm-3 at T = 300K. (a) Calculate the Fermi level on each side of the junction with respect to the intrinsic Fermi level.
Design a circuit that, given a 2-bit value, will light a LED corresponding to that value. One of four LEDs should be lit for each of the four possible input values (binary 0 through 3).
A three-bit Johnson counter is clocked with pulses at a 120 MHz rate. What will be the pulse frequency of the output of the last flip-flop in the chain. Ten pulses are applied to a four-bit asynchronous counter. If the counter state was 0000 befor..
Two homogeneous isotropic dielectrics meet on plane x=0. For x > 0, Er1=6 and for x 0. Find: a) E2 for x
Show that for wires of identical dimensions but made of different materials, such as copper and aluminum, the resistance is proportional to the resistivity of the material. the resistance of a certain copper wire is 1.5.
