What is total voltage in 3phase supply when one of the phase becomes zero?
There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.
What to do if Water valve knob won't turn back on?
Isolate it from the water supply then replace the defective valve
What does isolate washing machine water supply mean?
It means to shut off the water feed to the washing machine.
What is use of RFC in Hartley oscillator?
it is a radio frequency choke which connects the dc supply to the circuit but isolate the dc supply from the high frequency oscillations generated in the feedback circuit
Why capacitors cannot be used with direct current?
DC does not travel through a capacitor for long because there is a buildup of charge on the plates and when the voltage matches the supply voltage, mo more current flows. But capacitors are used to smooth a DC supply because a capacitor acts a bit like a small battery and can prevent any rapid fluctuations in the supply voltage.
Where are capacitors used?
Capacitors are used in many different ways.Here are a few instances where they are used:in amplifier circuits to isolate small signal circuitry from amplifier circuits' DC biasin power supplies to minimize AC ripple on the DC waveformin timer circuits to create specific patterns and frequencieswith integrated circuits to prevent ripple from the power supply from reaching the ICin analog computation machines for creating integrators and differentiatorsin high voltage AC systems to "add VARs" to the system.
Are capacitors and inductors active elements?
Capacitors and inductors are considered passive elements, not active elements, because capacitors and inductors do not supply or amplify energy. An example of an active element is a battery, which supplies energy to a circuit.
Why are capacitors parallel?
Capacitors are said to be connected together "in parallel" when both of their terminals are respectively connected to each terminal of the other capacitor or capacitors. The voltage (Vc ) connected across all the capacitors that are connected in parallel is THE SAME. Then,Capacitors in Parallel have a "common voltage" supply across them giving: VC1 = VC2 = VC3 = VAB = 12V
How do you get the buzz out of the Magnivox radio 1970s?
Here's one possibility ... no guarantee: Radios of that era used large-value electrolytic capacitors in their power supply filters. These capacitors can deteriorate over time, allowing AC-ripple out of the power supply, which is then clearly audible in the audio stages. Take the radio to a TV-repair shop or a friend familiar with electronics construction, and ask them to replace the electrolytic capacitors in the power supply.
What should be used in the failure of stop valve to isolate the supply from outside tap on cold water supply?
Stop Valve Key
What is theloud buzz when you turn on radio Magnivox early 1970 model 2540A?

What will happen if dc is applied to the series and parallel combination of capacitors?
a capacitor must be supplied with only a.c supply because if it is supplied with d.c.supply the distance between the capacitors increases and it acts as a open circuit.
Why does my LCD TV have no power all of a sudden?
Could Be a fuse on the Circuit Board or The Power Supply Capacitors are bad.

What to do if Water valve knob won't turn back on?
Isolate it from the water supply then replace the defective valve
Why use capacitors on fan motors?
capacitor stores charge ,so we use capacitor in fan for continuous voltage supply.
How do you troubleshoot home air condition compressor?
check starting capacitors. Check voltage supply with a voltmenter from outlet to compressor.
