An AAC is composed of 37 strands, each having a diameter of 0.333 cm. Compute the dc resistance in ohms per kilometer at 75°C. Assume that the increase in resistance due to spirtling is 2%.
Determine the volumes of each of these semiconductors that will on avg contain one hole. The intrinsic carrier concentrations are ni=1.02*10^10 cm^-3,ni= 2.1*10^ cm^-3, and 10^-7 cm^-3.
A spherical capacitor is formed from two concentric spherical conducting shells separated by vacuum. The inner sphere has radius 10.0 centimeters, and the separation between the spheres is 1.50 centimeters.
Voltage v(t) = 4e-20tV for t > 0 is input to the circuit. The resultant current i(t) = -1.2e-20t - 1.5 A. The initial inductor current iL(0) = -3.5A. Find the values of the inductance L and the resistance R in the circuit.
A 40 H resistor, a 5 mH inductor, and a 1.25/xF capacitor are connected in series. The series-connected elements are energized by a sinusoidal voltage source whose voltage is 600 cos (8000t + 20°)V. a) Draw the frequency-domain equivalent circuit.
the specific heat of water is 4.18x10^3 J/kg(deg)C, so a mass ofwater M (in kilograms) heated by a power P (watts) undergoes a risein temp. at a rate given by: dT/dt = (2.39x10^-4 P)/(M) degrees C/s assuming that the mass of an arm is 4kg, the mass..
Model the actual resistive value R0 of a resistor marked as 100 ? with a 5% tolerance as a uniform random variable R0 over the range [95, 105] ?.
An AC Voltmeter uses a bridge rectifier and 100 ohm PMMC which requires a 1mA DC current for full-scale deflection. Assuming ideal diodes, calculate the value of the multiplier resistor to obtain full scale deflection with 10 V AC applied to the i..
The microphone of the headset is producing scratchy noises due to movements while running and moving.
Two amplifiers are cascaded, one with a voltage gain of 6 db and the other with a voltage gain of 4. If 1 V is applied at the input of the first amplifier, what is the voltage at the output of the second amplifier
The LM358 op amp can be a single or dual supply op-amp. This mean that it can operate with just a single supply i.e. + 5 volt or with dual supplies i.e. (+ and -) 5 volt supplies. With a non-inverting configuration with dual supplies (+5v and -5v)..
A nnpn transistor has an emitter area of 10mm x10mm. The dopingconcentrations are as follows: in the emitterNd=1019 cm3, in the baseNa=1017 cm3, and the collectorNd=1015 cm3. The transistoris operating at T=300K.
They are separated by a distance equal to their radiusR. They each have N turns and carry equalcurrents I in the same direction. Calculate the field strength if the loops are 11 cm india meter, have 14 turns, and carry a 1.8 A current.
