What is the instantaneous voltage at 180 degrees for peak voltage of 150 volts?
Zero. If voltage starts at zero at zero degrees, it rises to peak voltage at 90 degrees. Voltage then reaches zero at 180 degrees and heads for negative peak voltage at 270 degrees and then back to zero at 360 degrees.
What is the instantaneous voltage of a sine wave at 25 degrees if its peak voltage is 30 V?
12.68V 3o * sin25 = 12.67854785
How is low voltage circuit normally protected?
If it is then it has a 3 or 5 amp fuse. Some are not.
What is the voltage regulation of an ideal transformer?
Ideally the voltage regulation voltage of a transformer should be zero. It means when you change the load from no load to short circuit (theoretically, normally you don't want to burn the transformer windings) the output voltage doesn't change and remains equal to the no load voltage.
What angle is the voltage increasing at its fastest rate?
This is a simple derivation problem. Take the derivative of the AC voltage waveform (I'll assume sin (t)), and set the derivative equal to the maximum value it can attain (which is 1): cos (t) = 1, t = 0 degrees, thus for an AC waveform of y = sin(t), the fastest increase in voltage occurs at 0, 360, etc. degrees. The fastest decrease in voltage will occur at 180, 180 + 360, etc. degrees.
How does time relate to degrees in an AC sine wave?
One cycle of the sine wave is equal to 360 degrees. In US the frequency of power is typically 60 Hz and hence one cycle is 1/60 of a second. Therefore you can calculate the degrees at any instant of time. If at zero degrees the voltage amplitude is zero, then at 90 degrees,which is 1/4 cycle, wave is at peak voltage. At 180 degrees it is at 1/2 cycle and zero voltage and then at 270 degrees it is 3/4 of the cycle and a peak negative voltage. Finally at 360 degrees the cycle is complete and the voltage is again zero.
What is the instantaneous voltage at 180 degrees for peak voltage of 150 volts?
Zero. If voltage starts at zero at zero degrees, it rises to peak voltage at 90 degrees. Voltage then reaches zero at 180 degrees and heads for negative peak voltage at 270 degrees and then back to zero at 360 degrees.
How many degrees are the current and voltage out of phase in a pure capacitive circuit?
In a pure (ideal) capacitive circuit, current leads voltage by 90 degrees.
What is the voltage at the 90 degree point of a sine wave with a maximum voltage of 10 volts?
10 Volts. ANSWER: ASSUMING a start when the voltage is at 0 and 0 degrees at 90 degrees is at maximum at 180 degrees is again at 0 v at 270 degrees is at the maximum negative potential and at 360 degrees is again at 0 v. the voltage is irrelevant in any case but it will follow these rules
What is the voltage at 90 degrees if the instantaneous voltage is 225v at 60 degree angle?
To find the voltage at 90 degrees given an instantaneous voltage of 225 V at a 60-degree angle, we can assume a sinusoidal function for the voltage. The voltage can be represented as ( V(t) = V_m \sin(\theta) ), where ( V_m ) is the maximum voltage. Since you provided the instantaneous voltage at 60 degrees, you can calculate the maximum voltage ( V_m ) using ( V_m = \frac{225}{\sin(60^\circ)} ). Then, to find the voltage at 90 degrees, you would evaluate ( V(t) ) at that angle, resulting in ( V(90^\circ) = V_m \sin(90^\circ) = V_m ).
Does a bigger sized battery have a greater voltage?
A larger voltage rating: yes, of course. A larger size rating: these are not normally related to the voltage rating, which is separate. A larger physical size: normally this means a greater voltage, but again, they are not directly related to the voltage rating. Size has nothing to do with voltage. Battery voltage is controlled by the number of cells in the battery. Plate size affects current delivery.
How can you inactivate a voltage source?
Disconnect it (that's what a switch normally does).
On a 110 voltage circuit where the white wire is common the black wire is normally?
The voltage potential supplying conductor.
If an AC voltage begins rising or going positive at 0 degrees when will it reach its maximum negative value?
It's a sine wave (if there is no distortion). Voltage is zero at 0 degrees, at its positive peak at 90 degrees, back to zero at 180 degrees, at its negative peak at 270 degrees, and back to zero at 360 degrees.
What is the practical purpose of a voltage converter?
A voltage converted can allow you to use electronics from other countries that you wouldn't normally use. Also, incorrect voltage can damage machines.
What is the instantaneous voltage of 90 degrees?
The instantaneous voltage at 90 degrees in a sinusoidal waveform is at its peak value, as this angle corresponds to the maximum point of the sine function. Mathematically, if the voltage is represented as ( V(t) = V_{\text{max}} \sin(\omega t + \phi) ), at 90 degrees (or ( \frac{\pi}{2} ) radians), the voltage is ( V(t) = V_{\text{max}} ). Thus, the instantaneous voltage is equal to the maximum amplitude of the waveform.
What is status of a circuit that is complete and unbroken with flowing electric current?
A circuit that is complete and unbroken with flowing electric current normally has steady supply of voltage with no broken links. Electrical energy flows to light up a bulb or do similar work. Its status is complete, nothing else is needed.
