Assume that you have bought a solar based decorative lamp for your house during a festival time. You are finding the given diagram inside the information booklet.Also it is mentioned in the booklet that the lamp lits when 12 50mA but will burnout when 12 75mA and the lamp resistance is 2000 milli ohms.Surprisingly, when you open the control circuit you did not find the component "R". But as a electrical student you have decided by yourself to design and connect the same to the circuit. How are you going to select the range of required value so that the lamp will lit but will not burnout even if "R" is changed by +10% as a result of temperature changes in the room.

You are working as an electrician in a large steel manufacturing plant, and you are in the process of doing preventive maintenance on a large DC generator. You have megged both the series and shunt field windings and found that each has over 10 M to ground. Your ohmmeter, however, indicates a resistance of 1.5 across terminals S1andS2. The ohmmeter indicates a resistance of 225 between terminals F1andF2. Are these readings normal for this type machine, or is there a likely problem? Explain your answer.
An AC electric motor is connected to a 240-V, 60-Hz source. A clamp-on ammeter with a peak hold function reveals that the motor has an inrush current of 34 A when the motor is first started. Your job is to reduce the inrush current to a value of 20 A by connecting a resistor in series with the motor. The resistor will be shunted out of the circuit after the motor is started. Using an ohmmeter, you find that the motor has a wire resistance of 3 . How much resistance should be connected in series with the motor to reduce the starting current to 20 A?
In an R-L parallel circuit, ET=208 volts, R=2.4k, and XL=1.8k. Find IT.
Lightbulbs are rated by their power consumption in watts (W). Electricity is sold in units of energy, which is power multiplied by time. Electricity costs vary widely across the United States and are on the order of 0.08–0.30 $/kW-hr for residential customers. Create a spreadsheet that utilizes electricity costs and the number of hours per day that a lightbulb is on as input variables. Then calculate the annual cost to operate a 60-W, 75-W, and 100-W incandescent bulb and the equivalent LED bulbs consuming 8, 10, and 16 W, respectively. Assuming the average household operates six 60-W, four 75-W, and two 100-W incandescent bulbs for 6 hours a day, how much money can they save in a year by changing all the bulbs to equivalent LED bulbs?
Basic Electrical Engineering You have been sent to a new home. The homeowner reports that sometimes the electric furnace trips the 240-V, 60-A circuit breaker connected to it. Upon examination, you find that the furnace contains three 5000-W heating elements designed to turn on in stages. For example, when the thermostat calls for heat, the first 5000-W unit turns on. After some period of time, the second unit will turn on, and then, after another time delay, the third unit will turn on. What do you think the problem is, and so would your recommendation for correcting? Explain your answer.
4. The heating element in an oven has a resistance of R =32 ohms. One of thewires connecting the oven to the 220 volt power source is loose, contributingan additional r = 5 ohms to the closed-loop circuit. What is the power Povenradiated in the oven, and what is the rate Pcontact at which heat is dissipatedat the loose contact? The looser is the connection, the greater is the resistance r: What value of r is most likely to cause a fire. Also agraph showing Pcontact versus r

Find the values of input and output power. The weight of the car is 800 Kg The weight of each person is 75 Kg You may assume any missing parameters you need in the design appropriately (e.g., the rolling-resistance-power, air-resistance-power, the DC motor's parameters, ....etc)
Q) Since VDD=+15 V, VTH= +2 V and K= 100mA/V^2 in the circuit below, what is the ID current? (R value specified in resistors in the circuit is ohm expression) NOT : I found the value of the current Id and it was 16 m A , but it was not there in the options, so I want to know what the correct answer is, although the options contain the voltage and required in the current question. Is there an error, and if the error is present, I want to answer the question to know what is required. please
The open-circuit voltage of a particular solar cell is 2.2 V, and the short-circuit resistance (that is, a load resistor is zero) is 1.1 A. What is the internal resistance of the battery? What is the voltage supplied by the battery?
This is a practice question from my Signals and Systems course in my Electrical and Computer Engineering program. Could you please walk me through the process of how to solve this problem. Thank you very much for your assistance.
