A 2400-115 V transformer has a sinusoidal flux expressed by φ =0.113 sin 188.5t. Determine the primary and secondary turns.
Design a common collector circuit using a npn silicon transistor having Beta=90 with Vcc=20 V The desired Q-point is Vce=14V and Ie=2mA
if we have a signal source impedance that is almost as high as the input impedance of the inverting Op Amp (Rin) what effect would that have. How much signal would appear at the inverting input of the Op Amp.
Look at the resistor illustrated. Based on your knowledge of the resistor color code, what are the resistance value and tolerance of this resistor?
An input signal of 10V at 0o and a frequency of 1592 Hz is applied to a series RLC circuit with resistor R = 100 ohm, inductor L = 20 mH, and capacitor C = 0.5 F. The value of the total circuit complex impedance is.
How would you determine whether a given function, f(t), had finite or infinite energy. Give an example of a function with finite energy and one with infinite energy.
Calculate the gain of an inverting amplifier with Rs = 100kO and Rf = 500kO. Assume the op amp is ideal. Calculate the gain of an inverting amplifier with Rs = 100kO and Rf = 500kO.
What should be the capacitance of a capacitor, in series with a 250-ohm resistor, that will limit the current to 1.2 A when the circuit is connected to a 600 V 60-cycle source
Two charged particles, Q1 = +5.50 nC and Q2 = -3.40 nC, are separated by 39.0 cm. (a) What is the electrical potential energy of the pair (b) What is the electric potential at a point midway between the charged particles
A permanent magnet dc motor is delivering zero torque when it runs at 1800 rev/min and has 50 V dc applied to its terminals. The armature resistance is 2.0 ohm. What current will the motor need in order to deliver a torque of 2.0 Nm
A thyristor is triggered by a pulse of train of 5kHz.The duty ratio of the pulse train are 0.5. If allowable average gate power is 100W, calculate the maximum allowable gate drive power.
The potentiometer is designed to rotate 330 degrees to give the full range of possible resistance. However, the actual measurement range that is used is only 165 degrees indicating positions of a liquid sensor float ranging from 0 to 10 cm (empty ..
The collector current was measured for different values of load resistance. It was noticed that the collector current was pretty much constant for the first 1900 ohms and then it fell drastically.
