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

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

approval. In July 1994 FDA advisors recommended against allowing JJM to sell Pepcid AC‚ a reduced strength form of Pepcid‚ as an OTC drug. Problems/Opportunities: The major hurdle in launching Pepcid AC as an OTC drug was getting it approved by FDA. JJM pursued. Tagamet had an early lead in the FDA approval process. JJM was pursuing a strategy comprising of both a treatment and a prevention claim to launch Pepcid AC in the OTC market. However‚ FDA advisory committee rejected SmithKline Beecham
