correctly indicate an alternating current. There are‚ however‚ four basic types of meter movement that will indicate ac values:- Thermocouple Hot wire Electrodynamometer Iron-vane Electrodynamic ammeters An electrodynamic meter uses an electromagnet instead of the permanent magnet. This instrument can respond to both alternating and direct current and also indicates true RMS for AC. Principle of working The operation is basically based on the mechanical interaction between two conductors

The path I have chosen to take in my life is pursuing a career in the medical field. I am a people person‚ and I love to take care of others. Helping people reach a goal is very rewarding. I am so happy that OTC has a nursing program. I plan to take all of the necessary requirements to become a nurse. I know that the program is hard to get into‚ but I plan to achieve this. I know that there are limited spots‚ but am willing to prove myself. I know that it will not be easy‚ but that is a risk I

Chapter 13 AC MEASUREMENT This chapter explains rectification for measurement and rectifying instruments. Knowledge of the circuit principles will help you use these instruments properly and measurements alternating current correctly. One of the most common and economical methods for measuring alternating currents is to rectify these currents and read the resultant DC on an analog or digital volt-ohm meter (VOM). You need to take many considerations into account when using rectification: what

Alternating Current Theory - J R Lucas An alternating waveform is a periodic waveform which alternate between positive and negative values. Unlike direct waveforms‚ they cannot be characterised by one magnitude as their amplitude is continuously varying from instant to instant. Thus various forms of magnitudes are defined for such waveforms. The advantage of the alternating waveform for electric power is that it can be stepped up or stepped down in potential easily for transmission and utilisation

The word race comes from a Norse word.[1] This Norse word arrived in France during the invading of Normandy and gave the word raz which means "swift water" in Brittany‚ as in a mill race; it can be found in "Pointe du Raz" (the most western point of France‚ in Brittany)‚ and "raz-de-marée" (tsunami). The word race to mean a "contest of speed" was first recorded in the 1510s.[2] A race and its name are often associated with the place of origin‚ the means of transport and the distance of the race

Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are common and connected with significant morbidity and mortality among critically ill adults (1-4). The World Society of abdominal compartment syndrome (WSACS) accord report in 2004 indicated that in the critically ill patient‚ the IAP is frequently elevated above patient’s normal baseline which is roughly 5 to 7 mmHg (1‚3). Increased IAP or Intra-abdominal hypertension (IAH) described as a sustained or repeated pathological

Street racing is an illegal sport that is growing popular at an alarming rate. Street racing is the concept of high performance automobliles racing on public roadways illegally. Individuals will take a basic car and tune it up to be very quick and very powerful. The idea of street racing originates from the legal sport of drag racing. Drag racing is an internationally recognized sport governed by the NHRA‚ the National Hot Rod Association. Drag racing consist of two drivers in separate cars

Discussion In the experiment AC circuits‚ the purpose was to see the effect that a capacitor‚ resistor‚ and inductor have on the voltage‚ and current of a circuit. We created circuits with 2 resistors‚ a capacitor and a resistor‚ and then a capacitor‚ resistor‚ and an inductor. The circuits were then hooked up to a function generator‚ and oscilloscope to find the voltage across certain frequencies and then calculate the peak current‚ capacitive reactance or the inductive reactance‚ and phase difference

Kirsten Wilkie Should horse racing be banned? Just an animal‚ only a horse‚ there are plenty more. I think not! Horses should not have to suffer beneath the glamorous façade‚ which is commercial horse racing. Motivated by financial gain and prestige company‚ most people regard it as a harmless and entertaining sport; but would the public still think that if they knew the truth? Behind the scenes‚ lies a story of immense suffering and complications. The standard whip
