Another A.C circuit question =/

Not sure if the answer to this will be as easy as the last one i) The impedance of teh capactiro expressed in polar form. A) Cz = V/i = 79.62 = 31.848 ii) The capacitance of the capacitor A) C =

When calculating the Gain in voltage (Vout/Vs) What does "Vout" represent in the circuit

this Gain formula is associated with amplifier circuits and I think you have a slightly different formula than what is normally used... by Vs you mean supply voltage, this can cause confusion since t

Is HVAC part of Mechanical Engineering?-YES-yeah it can be, Depending on where you...some courses are strictly on building services which take a deeper look into HVAC services. But you can do Mechani

What is the purpose of condensate storage tank in thermal power plant and how it works

The condensate storage tanks collect the condensate produced from the steam that is generated in the power plant and distributed for various uses within the plant. When the steam is used it condenses

How to make the switch work on a flashlight

Okay, so i need help making my built flashlight turn on and off. I dont know what to connect it to so can someone please help me figure out what to connect it to. I built the switch with aluminum foil

How do I build a time machine

Or an alternate reality machine? I want to go to Middle Earth.-To get to Middle Earth I always just drive to Northern Earth and then turn south and keep going until just past the detour sign then par

Determine the value of i^325

Please help and explain(: Thanks!-you are referring to i = sqrt (-1) I presume i^1 = i i^2= -1 i^3=i^2 i = -i i^4=i^2 i^2 = (-1) (-1) = 1 i^5=i^4 i =i and so on...see the pattern ? so to find i^325

Meaning of LEED. in Engineering (Building)

Meaning of LEED?-Leadership in Energy and Environmental Design-leadership in energy and environmental design. its a certificate given to buildings on how well they perform through energy efficiency.

Solve this problem: a chiller is rated 1500TR and has an efficiency of 0.65kw/TR, What is the Condenser Heat R

Qc = [(COP + 1) / COP] Qe Qe = 1500TR = 5280 kW COP = 3.52 / 0.65kw/TR = 5.415 Therefore: Qc = 6255kW or 1777 TR

Can connect the Diode IN4007 for rectification with 240V AC directly without any resistor

Average Rectified Output Current should not one ampere.-Yes. Because its PIV (Peak Inverse Voltage) 1000V.(700Vrms) Besides, its generally a bad practice to put resistors in rectifier circuits.Its bet

Is it possible to have a large current from the SCR's gate below

With the SCR is on, S1 is open and increase R2 util the SCR switch off. The measurement of the SCRs gate is around 101mA, gate voltage is 0.778, holding current 16mA and forward voltage is 1.92V. htt
