I am comfortable picking up a new coding language if need be. I would really appreciate recommendations for prototyping and learning resources. I also have an Arduino kit, but I am still very much a novice when it comes to hardware. I have played around with Raspberry Pie and Particle boards a tiny bit. I am hoping it might be possible to have a device that could last for months to years. GPS would be nice to have, but not at the expense of battery life. I am assuming that I would need an accelerometer, a lithium battery, and a way to connect it to cellular data. Calculate voltages, currents, or resistances with Ohm’s law. 20.2.Ohm’s Law: Resistance and Simple Circuits Explain the origin of Ohm’s law. Use drift velocity to calculate current and vice versa. I want to know if it has been flipped over. Define electric current, ampere, and drift velocity Describe the direction of charge flow in conventional current. At that point it should send a call to an API with information about its position in space. If you are author or own the copyright of this book, please report to us by using this DMCA report form.

I am looking for advice about different products and resources to help me achieve this goal.īasically, I want this device to sit "asleep" in the environment until it is physically handled. Download Basic Electrical Engineering V.k.mehta E S.chand. I want to build/find a device that can last a very long time on a single charge and notify an API if it is physically moved. * From this example value,we can determine our electric motor load in good condition.It is 100% with output power to drive the equipment.It efficiency and not to run with overload.Hello, I am a software engineer and hobbyist maker and I am looking to get more into hardware. Output power as a % of rated power = 107.4% V red = 462 volt V blue = 461 volt V yellow = 460 volt We can quantify the motor’s part-load by comparing the measured input power under load to the power required when the motor operates at rated capacity using this formula.įirst step for actual value of voltage and ampere,i suggest to collected measurement data from motor using the Voltmeter and Clamp on meter.Example as following :- the National Electrical Manufacturers Association (NEMA), the Aerospace Industries Association (AIA). We need to determine the full rated load in kW We determine value of power in kW (Pi) using this formula. We have 1 unit Induction Motor with 30 horsepower (hp),running with 34.9 amps for amperage load and 460 volts 3 phase and power factor value is 0.75 and motor efficiency is 85% It is combination from Amperage and Voltage value.Basic formula for Power is P (watt) =I(ampere) x V (volt).Power also measured in Horsepower (hp) unit.For common conversion from electrical Horsepower to Watt is 1hp = 746 watt.Įlectrical motor loads are calculated from power in kW and full rated load in kW.Following is the formula how to calculate Motor loads. What is meaning of Power?Of course this term is significant with our discussion topic.Power is rated of energy in electrical circuit. On my last post,i discussed about why we need to determine motor loads and efficiency.So for this post i want to share how to get the motor load value using simple calculation electrical formula.īefore we go further,i want to explain about Power. GENERAL ENGINEERING ISM-RF Baseband Calculator (XLS, 202kB), Can be used to calculate the filter capacitor values and the data slicer RC components of an.
