An electric heater is connected to a constant 240-V source and absorbs 1000 W. Subsequently, this heater is connected to a constant 210-V source.
(a) What is the resistance of the heater?
(b)What power does it absorb from the 210-V source?
Design a 7.5-V zener regulator circuit using a 7.5-V zener specified at 12mA. The zener has an incremental resistance r(z) = 30 ohms and a knee current of 0.5mA. The regulator operates from a 10-V supply and has a 1.2k-ohm load.
The loop transfer function of a single-loop negative feedback system is: L(s) = Gc(s)G(s) = K(s + 2.5)(s + 3.2) / (s2(s + 1)(s + 10)(s + 30)) This system is called conditionally stable because it is stable only for a range of the gain K
If you were the operator for an squirrel cage induction machine, what options could you consider to control speed Describe and mention pluses and minuses of each.
In the absence of any special knowledge of network conditions, the typical approach is to pick an arbitrary value, such as 3 s, and hope that this will converge quickly to an accurate value. If this estimate is too small, TCP will perform unnecess..
Design a 16 bit adder using both the ripple carry and CLA methods. Use 4-bit CLA blocks for the carry-lookahead design. Use only two-input logic gates in your design. Simulate the design using LogiSim at the logic gate level.
a 14-bit successive approximation adc is used to sample a signal that has a full-scale range of 8V and a clock frequency of 12 MHz and a jitter of 50ns.initially this is used without a sample and hold amplifier.
The maximum oven temperature to be maintained by the conventional type of thermostatic control is 290 degrees Celsius, the kitchen temperature may vary from 15 to 33 degrees Celsius, and the average heat transfer coefficient between the oven surfac..
Write the magnitude function for a third order Chebyshev filter having a ripple coefficient of 0.4. Do not expand. Also find the cutoff frequency.
A unity feedback control systems for a robot submarine has a plant with a third-order transfer function G(s) = K / (s(s + 10)(s +50)) We want the overshoot to be approximately 7.5% for a step input
In a certain balanced three-phase system, each line current is 5A and each line voltage is 220 V. What is the approximatereal power, if the power factor is 0.7
Traffic lights are being converted from incandescent bulbs to LED arrays to save operating and maintenance costs. Typically each incandescent light uses three 100-W bulbs, one for each color R,Y,G,A competing LED array consists of 61 LEDs.
Begin with a breadboard, wire, an RGB LED and some resistors. Using the forward voltages given in the RGB LED datasheet, calculate the correct current-limiting resistors needed to light each color of the LED (assuming VDD = +5V).
