Hi fellow colleagues, please help me with this questions:
A food truck uses an electric generator driven by a gas engine to power all of the electric appliances. The generator output and the 220v voltage. It is known that the roulette uses 50 LED lamps each with a rated power of 5W and 2 fryers with nominal power of 2200w each. The food truck has two refrigerators that consume annually and together 480Kw / year. 1-Determine the power of each of the cold boxes. 2-Assuming that all the equipment is connected at the same time as the necessary electrical power? 3-What is the total power that the diesel engine should generate in this situation? 4-Calculate the maximum current that the generator must provide to guarantee the operation of the carriage. 5-If the car runs 8h / day what is the total energy consumed by the diesel engine for one year? 6-If the cost of diesel is 1.35 € / liter and the ratio of conversion in electric energy 1.15 kwh / liter, how much will be spent in a year in diesel?
1-Determine the currents that cross the elements with f.e.m 2-Say, justifying, if they are functioning as a source or receiver. 3-Draw the thevenin circuit for the bipolar AB, determining VTh and RTh. 4-Determine the contribution of the source E0 to the current in the branch of R2. 5- What is the value of the resistance to be placed between the points AB so that the electric power dissipated in it is 10W. Data: R0 = R1 = R2 = R3 = R4 = 6K (ohm) R5 = R7 = 3K (Ohm) R6 = 12k (ohm) E0 = 15v, E1 = 12v, E2 = 27v
The voltage source has an electromotive force of 10V. The components R1 and R2 have a value of 10ohm and 20ohm respectively. The value for the capacitors C, is 2 microfarad
1-Simplify the circuit indicated the values of the capacitors. 2-Determine the time constant of the circuit. Consider the originally downloaded condensers, switch K. Determine: 1-the initial charge current of the capacitors at the instant immediately after closing the K-switch. 2-Final charge voltage of the capacitor obtained by the association of capacitors. 3- How long does it take to reach 50% of the equiavalent capacitor load?
