1. How much power is represented by a circuit in which the voltage and current equations aree= 160 sin 314tandi= 42.5 sin 314t?
2. A coil of wire having negligible resistance and an inductance of 0.248 henry is connected to a 117-volt 50-cycle source. Calculate
(a) the inductive reactance,
(b) the current,
(c) the maximum power delivered to the inductor or
to sketch on common axis graphs to illustrate the response curve of secondary current against frequency when the
A metal detector is an electronic device that is able to detect the presence of nearby metallic objects. In this project a metal detecting probe will be designed, constructed and tested.
Obtain a timing diagram for a positive-edge-triggered JK master-slave flip-flop during four clock pulses. Show the timing diagrams for C, J, K, Q and Q'. Assume that before the first pulse: output Q is equal to 1, J=0 and K=1.
A) the required step-up voltage ratio for satisfactory performance. B) the voltage ratio of a standard buck-boost transformer that most closely meets the requirements of the load. C) the voltage at the load with the buck-boost transformer installed.
Two amplifiers(CS) connected in cascade. The input voltage to the first stage has a source voltage Vsig and Rsig= 100KOhm. Rv=10KOhm AND IS CONNECTED TO THE DRAIN OF THE SECOND STAGE. BOTH TRANSISTORS HAVE Id=.25mA and Vov=.25V
A torque of 18 N-m is applied to a rotating part. The moment of inertia is 0.078 kg-m2. How much time (in seconds) will it take to rotate the part 180°?
An analog-to-digital converter (ADC) samples an analog voltageand computes a digital value representing that voltage. Assume anADC accepts voltages between -1.0 V and +1.0 V and hte digitalvalues are 16-bit, two's complement fractions.
Let a crappy voice channel occupy 1kHz. To ensure no interefence between channels due to nonideal bandpass filters add a 3.0kHz spacing between channels. How many simultaneous voice channels can you have if allocated a 87MHz bandwidth total
At the instant shown, car A has a speed of 20km/h, which isbeing increased at a rate of 300km/h2 as the car entersan expressway. At the same instant, car B is decelerating at250 km/h2 while traveling forward at 100 km/h.
Older versions of CMOS devices may have had input gate capacitances of 10pF, logic levels of 0-5V, and propagation delays of 10 ns. With smaller physical sizes, the same function might have an inputgate capacitance of 2 pF and operate at logic lev..
a)What is the voltage across a 220? resistor if the current through it is 5.6 mA b)What is the current through a 6.8? resistor if the voltage drop across it is 24 V c) What is the power delivered by a 6 V battery if the current drain is 750mA
A 200 ft length of solid copper wire is measured to have a resistance of .500 Ohms. a. Determine the cross sectional area of the wire in both square mils and in circular mils. b. Determine the diameter of the wire in mils and in inches.
