A two-wire dc power distribution circuit supplies six 100 W lamps located 250 ft from a dc generator. The generator voltage is 120 V and the lamp voltage should be 110 V or more. Calculate the current drawn by each lamp if its voltage is 110 V and its power is 100 W. Calculate the current in the two-wire line. Calculate the maximum resistance of the two-wire line. Calculate the resistance per unit length (in ohms/1000 ft), keeping in mind that there are two wires each 250 ft long. What size of copper wire is required? use a table of wire resistance
Hint: Sketch the circuit using wire resistance as Rw. Assume the lamp voltage is 110 V, calculate the current to deliver 100 W to each lamp. Then calculate the line current Iline. Ohm's law and KVL will give equations that can be solved for Rw.
A 3-phase, 60 Hz supply and two 3-phase synchronous machines are available. Determine the speed, and a suitable number of poles, for each synchronous machine to provide: a) A 3-phase, 180 Hz supply. b) A 3-phase, 500 Hz supply.
In order to eliminate the cost of calling cards, the company in the above problem is considering a new policy that requires blocked callers to redial over and over until they get a trunk.
Discuss the sequence of actions that occur in the operation of the control system for a traffic light, that includes sensors in the roadbed. Indicate which actions are time-driven and which actions are event-driven
A sample of non-ideal gas is made to undergo an expansion process during which its pressure and volume are related as shown in the table below. The energy of the gas at the start and finish of the process is measured and found to be 5 and 3.2 Btu
A winding consists of 50 turns of a metallic conductor in a loop square with sides of 0.20 m in length each. The winding has center at the origin with two sides parallel to the axis of x the other two sides parallel to the y-axis
A long hallway has three doors, one at each end and one in the middle. A switch is located at each door to operate the incandescent lights along the hallway. Label the switches A, B, and C. Design a logic network to control the lights.
4 resistors are connected in electrical parallel. R1=2 OHM, R2= 4 OHM, R3= 6 OHM, R4= 8 OHM. if this parallel resistor combination is placed across an ideal current source = 3A.

Sketch the baseband signals for the two users when user 1 sends the bits 011, and user 2 sends the bits 101. Add the signals for the first bit only, and show that the output of the correlator for user 1 is -4, corresponding to a 0
A residential four-wire system supplies power at 220V rms to the following single-phase appliances: On the first phase, there are ten 75-W bulbs. On the second phase, there is a 750-W vacuum cleaner with a power factor of 0.87.
Instead of recreating the design every time we change the instruction ROM, we want to have a way to change the instructions while the system is running. Discuss how the UART can be used to fill an instruction RAM instead
Along the way to the page, they pass into a region between two deflecting plates that are 1.6 cm long. There is a 1,500,000 N/C electric field between the deflecting plates. You measure the distance from the edge of the plates to the paper and fin..
