Why apply in dc voltage in winding meggering time?
The DC between windings is analogous to DC on capacitor plates. Windings, like capacitors, require time to charge up to the applied voltage, at which, there will be a constant current. Since Voltage / current= Resistance, the Megohm reading will change/increase until the windings are fully charged to a quiescent, steady leakage current. When current is at a stable leakage level, you will have an accurate reading.

What is a carrier reinsertion oscillator?
A carrier reinsertion oscillator is an electronic circuit used in a radio receiver that is designed to receive single side band carried suppressed radio transmissions.
As suggested by the name, in a single side band carried suppressed signal, the carrier signal is suppressed (not transmitted) to save power and/or bandwidth.
Before the single side band carried suppressed signal can be decoded to extract the original audio signal, the carrier must first be reinserted. This must be done accurately, otherwise the recovered audio signal will be unintelligible.
Toshiba's top rivals is Hp and there lower ones (from greatest to least) Sony, Dell, Acer, Asus, etc.
Materials that are sometimes classified as insulators and sometimes as conductors are called?
semiconductors
What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.
What are Biological amplifiers in medical electronics?
Biological signal amplifiers are amplifiers designed to convert the weak voltage signal generated by various biological processes (nerve activity in EEGs, heart muscle activity in EKGs, etc.) into a strong signal.
Almost every biological signal amplifier is built from an integrated circuit instrumentation amplifier.
How do you use the fx loop on your mesa boogie dual rectifier roadster?
Detailed instructions read in the manual (can be retrieved from the Mesa website), but in short it is:
1. fx send -> effect input
2. effect output -> fx return
3. press the button on the footswitch to activate the loop
4. set the level send of the loop on the back
Special load in a circuit that slows down the flow of electrons?
Loads do not 'slow down' electron flow. They effect the magnitude of a current, not its speed!
What are the difference between LCR meter and electrochemical impedance spectroscopy?
LCR meter is a device. And electrochemical impedance spectroscopy is a method. So the difference between them are like the difference between pen and writing.
the white wire is your neutral side (ground usually), the small potential you're measuring is bleed current
What amplifier circuit is typically used as the input stage for an operational amplifier?
Differential amplifier
ANSWER: A differential amplifier is an op amp. If any amplification is required a preamplifier is used mainly to cut the white noise and improve the input impedance
Is a current relay same as potential relay?
current relay are using for over current low state & high state.but potential relay are related to voltage.
Does the device or cable determine the voltage on a slow cooker?
The voltage is always determined by the device. (in this case a slow cooker).
However, having established what voltage to supply to the device, the cable must be suitable for the voltage used. Everything in the chain of power transmission, must be rated for the correct voltage. Cables, plugs, fuses etc.
How can you download a free e-book?
A: There are places to download not necessarily e-books but certainly data sheets and application. Try any manufacture of components.
What ohms setting do you use on a meter for 240v electric heater?
Whenever you use an ohmmeter, you must first ensure that the device you want to test is disconnected from the supply. So the fact that your heater is rated at 240 V is irrelevant to this question. The heater must be disconnected from the supply BEFORE you contemplate measuring its resistance. Which 'ohms setting' to use is then simply determined by whichever setting gives you the best reading. For an analogue ohmmeter, this is whichever setting results in the pointer being towards the lower-resistance end of the scale.
What is the purpose of a CCTV multiplexer?
A CCTV Multiplexer is a device which is good for doing things such as connecting many security camera signals into one monitor for you to view them all at once.
How do you get barbie walkie talkie working?
Type your answer here... its working for half duplex methode and then can't communicate at the same time for two device or persion .ex: for the Tx persion one information send to the Rx persion , then completly received after Rx send the information to Tx.
