- Find I and V in the circuit of Fig. 2.82 correctly.arrow_forwardBasic Electrical Engineering A homeowner uses 100-watt incandescent lamps as a heater in an outside well pump house to protect the pump from freezing in cold weather. Unfortunately, however, the lamp can burn out and leave pump unprotected. You have been asked to install a hearth that will not burn out and leave the pump unprotected. You have available a 100-watt, 150-ohm wire-wound resistor. Can this resistor be connected to the 120-volt source without damage to the resistor? If so, what would be the power output of the resistor? (Hint: Use power formula)arrow_forwardIt is required to produce an illumination of 100 lux in a factory hall 30 m by 15 m. Assume that the maintenance factor is 0.8, coefficient of utilization is 0.4 and efficiency of lamp is 14 lm/W. Suggest the suitable rating, the number of lamps and their possible arrangement. The sizes of the lamps available are 100, 250, 400 and 500 W. [40 lamps of 250 W in 5 rows]arrow_forward
- Find the Norton equivalent circuit for the network external to the elements between a and b for the networks of Figure 2. all answers must be expressed in POLAR forms, and use 2 decimal places.arrow_forwardA family of three is considering to install solar water heater system. Each person needs 50 liters of water per day. They require a hot water with temperature of 50 °C from using tap water as a source with a typical temperature of 20 °C. Calculate the required heat energy to satisfy the family demand in a year, and calculate the required area of flat plate collector (its efficiency 40% with energy gain 540 kWh.m-2/ year) and evacuated tube collector (its efficiency 60% with energy gain 800 kWh.m-2/ year) that needs to be installed. Describe your answer.arrow_forwardConsider the circuit in Fig. 3 and perform the following: Calculate the voltage across each resistor and the current through each branch of the circuit. (Using Ohm’s law, KCL and KVL) Verify that the law of conservation of energy is satisfied by showing that the algebraic sum of power is zero.arrow_forward
- An Electric motor draws 11.04 W of power from a 20 V power supply when it is operating at its maximum capacity with 1.35 Amps of current flowing through it. A current limiting resistor (R2) is set to 15 Ohm to protect the motor from overheating. If a 2.2 W bulb with a resistance of 4 Ohms is put in parallel to the current limiting resistor, determine a suitable resistor value for R1 to protect the bulb from burning out.arrow_forward7. Find the equivalent resistance between points A and B of the circuit shown in Fig. 2.198.arrow_forwardWe have two small electric lamps on which it is written 8V, 1W. We have a 20V battery and negligible internal resistance. These two lamps, a resistor R and the current source are connected in series. (a) Calculate the value that R must have for the lamps to operate normally. (b) Calculate the efficiency of the systemarrow_forward
- Kindly solve what is ask. Provide complete solution and circuit diagram so that I can understand. Also, I want a handwritten solution. Thank you so much!arrow_forward3. By using repeated source transformations, find the value of voltage v in Fig. 2.87 (a). [8 V]arrow_forwardobserve the image attached of the circuit. calculate the ammount of power that is dissipated through the 3 Ω resisor in the circuit. your answer should have 2 decimal places.arrow_forward
