Where does the unintended resistance result?
The unintended resistance results a voltage drop
What are the possible result of a tap changer malfunction?
Low voltage, high voltage, or a fault; the effects of these could be damage to equipment, including the transformer and tap cahnger.
Why does higher applied voltage with the same resistance results in more current?
Ohm's law: Voltage = Amperes times Resistance. This means that increasing voltage while keeping resistance the same must result in an increase of current.
What happens to the current if the voltage is reduced by a factor of 3 and the resistance is constant?
Ohm's Law: V = I*R, so Voltage and Current are directly proportional and a change in voltage will result in a proportional change in current. (The current reduces by the same factor)
Definition of boost voltage?
As far as I know. Boost voltage or start voltage is a voltage increase that we use at low frequencies to compensate for the voltage lost. With no boost there would arise a flux which is to small. We would not be able to keep the demand of a constant magnetic flux, which result in losing the torque. The boost is responsible for maintaining the max torque at low frequency.
How do you explain the stability of output voltage in spite of input voltage changing at zener diode?
In the zener region of a diode, there is a relatively flat, low slope line for voltage as a function of current. As a result, increasing current in the zener region does not result in a significant increase in voltage - hence, voltage stability.
How many anps are in 21 kw?
It depends on the voltage; which depends on the country. If you know the voltage, divide the wattage by the voltage, the result is the amperage.
How much voltage loss with a dimmer switch when used for lights?
There is no loss in voltage. Voltage is constant (dependant on your supply). The dimming is as a result of of a reduction in current (ampage)
How many amps does a 34 watt flourescent bulb pull?
It depends on the voltage; which depends on the country. If you know the voltage, divide the wattage by the voltage, the result is the amperage.
Why Normal time-overcurrent relays are not adequate for generator backup protection?
Setting the time-overcurrent relays high enough to prevent tripping for normal overloads may result in them not tripping at all due to the decaying characteristic of the generator fault current. Using the system voltage to control the overcurrent characteristic resolves this problem, since the voltage should drop very little for overloads, but will collapse to a small value for external faults. The 51V protection function uses the system voltage to adapt the operation of a time overcurrent element, using either voltage-restraint (51VR) or voltage-control (51VC).
What do photovoltaic cells do?
It produces a DC voltage as a result of incident sunlight
Where does the unintended resistance result?
The unintended resistance results a voltage drop
What does a photovoltaic cell do?
It produces a DC voltage as a result of incident sunlight
What does anomalous results mean?
It is a result that does not fit the general pattern. so if the voltage was 2 and it picked up 4 paper clips and then the voltage was 4 and it picked up 8 paper clips and then the voltage was 6 but it picked up 3 paperclips it is clear to see that voltage 6 does not fit the general patternYour Welcome
Do batteries arranged in series produce greater amperage?
No. They will result in greater voltage.
How do you know that a variable is really a control variable and what is the property of control variables?
If you're performing an experiment in which your result depends on multiple variables, but you're just interested in how one of those variables effects the result, you would generally keep all of the other variables constant in order to negate their effects. Those variables that you're keeping constant are called control variables, and you would choose them based on the experiment. For example, say you wanted to determine how changes in resistance effect a circuit's current. Well, current is dependent on not only resistance, but voltage as well, and since you're only interested in the effects of resistance, you would make voltage the control variable, keeping it constant.
When It is required to calculate average voltage and when RMS voltage?
It is usually required in electrical examinations to make calculations. Simple answer to a complicated calculation. Remember, take peak to peak voltage and multiply by .707, the result being average voltage. This is the voltage that electrical test meters read.
