Why does the voltage drop rapidly on your tattoo machine?
Chances are good the capacitor is toast and needs to be changed.
What is difference between variable capacitor and fixed capacitor?
variable capacitors are those capacitors which can be intially or randomly canged by the user for example radio tunning.whereas fixed capacitors are those whose value is fixed and can't be changed. sohaib
What happen to the phase angle if the value of capacitor is fixed and the value of resistor is changed?
The phase angle will either go up or down as well, depending on the new value of the resistor.
How much resistance will an ohmmeter indicate across a good capacitor?
because resistance is restricting the current and voltage, so for it be accurate you need to know what the voltage and the amps are.AnswerCapacitance is quite independent of resistance and, therefore, it will NOT vary if resistance is changed.
Why does a single phase synchronous motor need a capacitor but for a three phase motor it is not required?
A three-phase motor has a rotating magnetic field inside that is set up by the supply, so the armature always rotates in the correct direction. A single-phase motor can in principle start either way so it has a starting winding supplied through a capacitor to provide a small component of rotating field to get it started the right way. After it has picked up speed the starting winding can be switched out.
What message do you receive when someone Verizon wireless phone is disconnected?
The number you dialed has been changed, disconnected or is no longer in service.
How potential energy is changed to kinetic energy?
potential energy is changed to kinetic energy when you push.
Which is faster to discharge or to charge a capacitor?
It depends on the amount of current available to charge or discharge. On the surface, I would say that you can discharge a capacitor faster than you can charge it, because the charge rate is limited by the current available in the power supply, while the discharge current could be quite high, because you could just apply a short circuit conductor around the capacitor. Of course, this could damage the capacitor. In truth, the equation of a capacitor is...dv/dt = i/C, which means that, given the same charge or discharge current, the rate of change of voltage would be the same.AnswerThe time taken to fully charge, or to fully discharge, a capacitor is given by the equation: time = 5 CR, where C represents its capacitance, in farads, and R represents the resistance of the circuit supplying the capacitor, in ohms. By 'fully charge', we mean bring the potential-difference across the capacitor's plates to the same value as the applied potential difference.If the external voltage source is replaced with a short circuit then, providing the resistance of the circuit hasn't changed, the discharge time will be exactly the same as the charging time. If the resistance is changed, then the same equation applies, but you need to insert the new value of resistance.

Do you have to rekey a key fob when battery is changed?
not if you replace the battery fairly quickly, it has built in capacitor which keeps its ower for a minute or so.
