How many degrees is an right angle?
90 degrees 90 degrees
What is the measure of an angle who's complement is 18 degrees?
90 - 18 = 72 degrees.90 - 18 = 72 degrees.90 - 18 = 72 degrees.90 - 18 = 72 degrees.
Is it possible to have adjacent angles that are also vertical angles and why?
Yes. Because 90+90 = 180 degrees. Yes. Because 90+90 = 180 degrees. Yes. Because 90+90 = 180 degrees. Yes. Because 90+90 = 180 degrees.
What is 90 degrees Celsius?
90 degrees C = 194 degrees F.
Two angles that measure 180 degrees?
90 degrees and 90 degrees
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 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 powerful mean?
The product of the instantaneous voltage and the instantaneous current for a circuit or component.
The phase angle between voltage and current in an a c circuit through a pure capacitance is?
90 degrees. In an AC circuit with a pure capacitance, the current leads the voltage by 90 degrees. This is because the current in a capacitor is proportional to the rate of change of voltage across it, leading to this phase relationship.
In a pure inductance circuit the current lags the voltage by what degree?
90 degrees
Solving problems on instantaneous voltage and current?
yes
What is the phase relationship of voltage across a capacitor and current though the capacitor?
In a capacitor, the current LEADS the voltage by 90 degrees, or to put it the other way, the voltage LAGS the current by 90 degrees. This is because the current in a capacitor depends on the RATE OF CHANGE in voltage across it, and the greatest rate of change is when the voltage is passing through zero (the sine-wave is at its steepest). So current will peak when the voltage is zero, and will be zero when the rate of change of voltage is zero - at the peak of the voltage waveform, when the waveform has stopped rising, and is about to start falling towards zero.
What is the approximate instantaneous voltage at 37 degrees on a 169 Vp sine wave?
169sin(37*) = 101.7067389 (round to 101.7) *=degrees (function found on TI Calculators under "Angle") you can not do like that generally VpSIN(Wt
Does the current lead or lag the voltage in a series A C circuit containing a large value of capacitance?
ICE current leads the voltage by 90 degrees.
Why current lead voltage in coil?
because a coil is an inductor,for current leads voltage in an inductorAnswerIt doesn't! Current lags voltage in a coil. In a purely-inductive circuit, the current lags the supply voltage by 90 degrees. The reason for this is 'self inductance'. Whenever a current changes, a voltage is induced into the coil which opposes that change in current. The maximum self-induced voltage occurs when the rate of change in current is greatest. The greatest positive rate of change of a.c. current occurs when that current is passing through the zero axis of its waveform, so the greatest (negative) induced voltage occurs at thatsame point, which is one-quarter of the wavelength, or 90 degrees. In accordance with Kirchhoff's Voltage Law, the supply voltage must be in antiphase with the induced voltage. So when the peak induced voltage is negative, the peak applied voltage must be positive. Or, to put it another way, the peak value of the applied voltage must occur 90 degrees before the peak value of the current -so the current lags the applied voltage by 90 degrees.
