Can a capacitor be used in the Thevenin Theorem?
Sure, but it won't mean anything unless the Thevenin source is an AC source. In that case, simply determine the frequency of the source, and draw the appropriate reactance in the circuit where the capacitor belongs. If the Thevenin source is DC, then the frequency is zero, the reactance of the capacitor is infinite, and you can show it as an open circuit, i.e. not there.
What are the dimensions of an isosceles triangle of least area that can be circumscribed about a circle of radius r?
The isosceles triangle of least area that can be circumscribed about a circle of radius r turns out to be not just isosceles, but also equilateral. Each side has length 2r x ( 3 )0.5 . The area is r2 x (27)0.5 . Thanks are due to litotes for pointing out that the original answer did not actually answer the question ! tpm Since the equilateral triangle is also an isosceles triangle, we can say that at least area that can be circumscribed to a circle is the area of an equilateral triangle.If we are talking only for isosceles triangle where base has different length than two congruent sides, we can say that at least area circumscribed to a circle with radius r, is the area of an isosceles triangle whose base angles are very close to 60 degrees. Solution: Let say that the isosceles triangle ABC is circumscribed to a circle with radius r, where BA = BC. We know that the center of the circle inscribed to a triangle is the point of the intersection of the three angle bisectors of the triangle. Let draw these angle bisectors, and denote with D the point where the bisector drawn from the vertex, B, of the triangle, intersects the base AC. Since the triangle is an isosceles triangle, then BD bisects the base and it is perpendicular to the base. So that AD = DC, OD = r, and the triangles ADB and AOD are right triangles (O is the center of the circle). In the triangle ADB, we have:tan A = BD/AD, so that AD = BD/tan A In the triangle AOD, we have:tan A/2 = OD/AD, so that AD = r/tan A/2, and AC = 2r/tan A/2 Therefore,BD/tan A = r/tan A/2, andBD = (r tan A)/tan A/2 Area of triangle ABC = (1/2)(AC)(BD) = (1/2)(2r/ tan A/2)[(r tan A)/tan A/2] = (r2 tan A)/tan2 A/2 After we try different acute angles measure, we see that the smallest area would be: If the angle A= 60⁰,then the Area of the triangle ABC = r2 tan 60⁰/tan2 30⁰ ≈ 5.1961r2 If the angle A= 59.8⁰,then the Area of the triangle ABC = (r2 tan 59.8⁰)/tan2 29.9⁰ ≈ 5.1962r2
What causes the outside AC compressor unit not come on after 7PM?
Improperly programmed programmable thermostat.
How can I effectively control the temperature in my home with one AC unit and two thermostats?
To effectively control the temperature in your home with one AC unit and two thermostats, you can set one thermostat to a lower temperature to activate the AC unit when it gets too warm, and set the other thermostat to a higher temperature to deactivate the AC unit when it reaches a comfortable level. This way, you can maintain a consistent temperature throughout your home by strategically adjusting the settings on each thermostat.
How can I effectively control the temperature in my home with 2 thermostats for one AC unit?
To effectively control the temperature in your home with 2 thermostats for one AC unit, you can set one thermostat as the primary control for the AC unit and the other as a secondary control. Ensure that both thermostats are set to the same temperature to avoid conflicting signals to the AC unit. Additionally, consider installing zoning systems to better regulate temperature in different areas of your home.
Can you have two thermostats for one AC unit?
yes, if the ac unit has 2 zones, you will need a thermostat for each zone. if the ac unit provides both ac and heat, you can connect a thermostat for each. not a good way to go. better to use 1 therm in that case that has a heat-cool switch on it so the unit is not putting out both heat and ac at the same time.
What is Cost of thermostat?
If you are looking for a programmable thermostat for your home, try Askarepairtech.com. They have good pricing.
What is the purpose of the thermostat wires outside the AC unit?
The purpose of the thermostat wires outside the AC unit is to connect the thermostat inside the building to the AC unit outside, allowing the thermostat to communicate with the AC unit and control its operation based on the desired temperature settings.
Can a faulty thermostat effect your central AC unit?
can a faluty thermostat affect your central ac working?
What are the best energy-efficient features to look for in a 220 AC window unit?
When looking for an energy-efficient 220 AC window unit, consider features like high Energy Efficiency Ratio (EER), programmable thermostat, and Energy Star certification. These features can help save energy and reduce electricity costs.
What are the key features and benefits of the Honeywell AC thermostat?
The key features of the Honeywell AC thermostat include programmable settings, Wi-Fi connectivity, and energy-saving capabilities. The benefits of this thermostat are increased comfort, convenience, and potential cost savings on energy bills.
Can I run two AC units with one thermostat?
I wanted to add some details: Currently I have two AC units on the roof that share returns and ducts, but are controlled by two thermostats separated by 2'. Can I run both units off the same thermostat? It seams no matter how I set the thermostats one unit ends up running more than the other. But maybe this is a good thing? Yes, you can operate both units from one thermostat. The best way would be to use a two stage thermostat. Then a relay will have to be installed in one of the units to separate the control transformers.
Why is my AC not working after changing the batteries in the thermostat?
There could be a few reasons why your AC is not working after changing the batteries in the thermostat. It's possible that the thermostat settings need to be adjusted or that there is a problem with the AC unit itself. It's best to check the thermostat settings and make sure they are correct, and if the issue persists, you may need to contact a professional to inspect the AC unit.
How do I connect thermostat wires to an AC unit?
To connect thermostat wires to an AC unit, first turn off the power to the unit. Then, match the wire colors from the thermostat to the corresponding terminals on the AC unit. Typically, the wires are connected to terminals labeled R, Y, G, and W. Use a screwdriver to secure the wires in place. Finally, turn the power back on and test the thermostat to ensure it is working properly.
