If an AC begins rising positive as 0 degrees when will it reach its negative maximum current?
Maximum negative current is at 270 degrees.
At what phase angle is the voltage momentarily constant in a sine wave?
We often see the peak and trough (maximum positive and maximum negative excursions) of the sine wave considered as points of momentarily constant voltage. Those points are at phase angles of 90 degrees and at 270 degrees.
Why voltage leads in Inductor?
Maximum induced voltage occurs when the current is changing at its greatest rate -this occurs when the current passes through zero. Since this voltage acts to oppose current flow, this maximum voltage acts in the negative sense when the current is acting in the positive direction. Since the supply voltage is equal, but opposite, the induced voltage, it is maximum when the current is zero -so leads by 90 degrees.
What is diode limiters?
AC, or alternating current, is when the current's voltage varies as a sine wave, say alternating from 120 V to -120 V with a period typically on the order of microseconds. Some devices, however, have a maximum current, typically much less than 120 V. In this case, a "diode limiter" is used. The diode limiter is essentially a circuit that does nothing when the voltage is between 0 V and whatever the maximum specified voltage is, but "clips" or "limits the voltage above that. So after, say, 20 V, the sine wave flattens out and is a straight line until it starts to decrease down to -20 V, at which point it becomes a flat line again. Such circuits are made by diodes (hence the name), which are primarily used for turning AC current into DC current.
What is maximum power rating?
Maximum power rating describes the maximum power at which a device can operate without reaching an excessive temperature. For example, in the case of a resistor, if its maximum power rating is exceeded, then it may burn out.
What is The magnitude of an alternation which varies from zero is called its?
I will first answer this from an electrical viewpoint. The maximum positive excursion from zero would be the PEAK, or MAXIMUM portion of the cycle. From a magnetic point, it would be POSITIVE. The negative excursion of the electrical cycle (below zero) would be the MINIMUM. It would be NEGATIVE from a magnetic perspective.
What is the Maximum Speed of the Jaguar XKR with the electronic limiter removed?
170 mph
What is the maximum and minimum of positive integers?
minimum is '0' and maximum cannot be defined
What is the maximum speed of Audi rs4?
A gentle electronic limiter draws a close on this headlong rush at 155mph. The gearing and power suggests that without this limiter, 180mph would be fairly easily achievable. ....it's about new model Shame i got up to 210 at the Neuberg in Germany ;)
Why is a wattage limiter used in a ceiling fan?
The federal government now requires that ceiling fan light kits be limited to a maximum of 190 watts. When the light is first turned on, a small current is passed through the bulbs and the wattage limiter, verifying that you have not exceeded the 190 watts.
Where would yoube if you were at the maximum latitude?
-- At the maximum positive latitude, you would be at the north pole. -- At the maximum negative latitude, you would be at the south pole.
If an AC begins rising positive as 0 degrees when will it reach its negative maximum current?
Maximum negative current is at 270 degrees.
How do you disconnect a rev limiter on a 2001 Blazer Xtreme?
Maximum RPMs are controlled by the PCM. Check with a speed shop to see if they have an aftermarket chip to replace the original. If you blow your engine, it would NOT be covered by warranty.
What can you say about the product of two positive integers?
The product will be a positive integer.It will be at least as large as the square of the minimum of the two numbers and at most as large as the square of their maximum.
Which group of Blood is maximum and minimum among people in the world?
B positive
What is the the relationship between population and sample parameter and statistic?
The relations depend on what measures. The sample mean is an unbiased estimate for the population mean, with maximum likelihood. The sample maximum is a lower bound for the population maximum.
If two positive numbers sum to N what must the numbers be so that their product is maximum?
Both must be the positive square root of N.
