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
Does battery voltage combine when you use more than one?
The voltage adds if you connect in series (positive to negative). It stays the same if in parallel (Positive to Positive and Negative to Negative).
How much time is the maximum positive current behind the maximum positive voltage when the current lags the voltage by 90 degrees?
It depends on the periodic time of the supply which, in turn, is determined by the supply frequency. So, work out the periodic time of a 50 or 60-Hz waveform, and go from there.
Why negative supply is more prefer then positive supply?
A: actually it is the other way around usually negative voltage is a biasing scheme. Most design are begun with a positive voltage in mind. Not that a negative voltage will not work it is just people think positive
How do you Verifypositive and negative wires with a multimeter?
To verify positive and negative wires with a multimeter, set the multimeter to the DC voltage setting. Connect the black probe to the negative terminal (common), and the red probe to the wire you want to test. If the multimeter displays a positive voltage, the wire is positive; if it shows a negative voltage, the wire is negative. If the reading is zero or close to it, the wire may not be energized.
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 are the meanings of positive and negative reduction potentials?
the meanings of positive and negative voltage

What is a positive DC voltage?
A positive DC voltage is an electric potential where excess electrons will flow from negative to positive.AnswerYou appear to be mixing up potential difference (i.e. voltage) with potential. There is no such thing as a 'positive' voltage if you mean 'positive' in the sense of charge! 'Voltage' means 'potential difference', and you cannot have a positive or negative potential difference in this sense. You can only apply positive and negative in this sense to potentials.However, if you mean 'positive' in the sense of direction, then a positive voltage is one that is acting in the opposite direction to a negative voltage within the same circuit. For example, where two batteries have been connected in opposition.
What is the difference between the positive clipper and negative clipper?
Positive clipper-the clipper which removes the positive half cycles of the input voltage, while the negative clipper the clipper which removes the negative half cycles of the input voltage.
You are wiring a LED lamp through a transformer you have a polarized plug and you know positive and negative The transformer is marked live and neutral Does live correspond with positive or negative?
LED's are DC voltage. Transformers are AC voltage. There is no positive or negative on AC voltage. You would need a diode to change the AC to DC, then there would be positive and negative voltages.
What is the maximum voltage across unbiased positive silicon diodes limiter during positive alternation of the input voltage?
0.7 V
What is an electrolytics cell?
A cell with a negative voltage charge.
