I don't know how long ago you asked this question but if you'd like a current value on your Bernina Virtuosa 150 QE machine, please go to a sewing store that specializes in selling Bernina machines. Ask them your question as they have a blue book. This book will give you the current trade in, and selling value. I hope this helps
Not sure what you mean by Class A current. Normally, when measuring AC voltage or current you either measure the peak to peak value or the Root Mean Squared (RMS) value. Since RMS is essentially an average measured over time, it would always be less than Peak to Peak value.
44 cents as of 2009
It is a forever stamp. It is good for the current value of a first class stamp.
There is no set price for the class D amp. The value of a specific amp would need to be determined, based on the condition of the item and where it was being sold.
Around £13 (Multiply by around 80 for current value)
Whatever the current First Class postage rate is. In March of 2012, that is 45 cents.

The class interval is the maximum possible value in the class less the maximum possible value in the class below. The second is equivalent to the minimum possible value in the class.
i think average value of current in ac current is zero.
Either the actual value of something, or the value of a current. It really depends on the context.
