Does it matter if the voltage leads the current or the current leads the voltage?
Yes. If voltage leads the current, the impedance is inductive (this would be the case if the load is a motor). If current leads the voltage, the impedance is capacitive (this would be the case for a CFL light bulb).
Does voltage matter when charging a capacitor?
Yes, voltage matters when charging a capacitor. Capacitor charge rate is proportional to current and inversely proportional to capacitance. dv/dt = i/c So, voltage matters in terms of charge rate, if you are simply using a resistor to limit the current flow, because a larger voltage will attempt to charge faster, and sometimes there is a limit on the current through a capacitor. There is also a limit on voltage across a capacitor, so a larger voltage could potentially damage the capacitor.
Why the voltage is same in parallel connections?
The voltage is the same across parallel inductors for the same reason its the same across parallel anythings - resistors - capacitors - transformers - whatevers. Parallel means sharing common connections to another part of the circuit. That sharing involves conductors that have essentially zero impedance. (Zero for all practical considerations) In order for there to be a different voltage across those parallel components, the conductors connecting them together must have something other than zero impedance, and then we would not be talking about parallel anymore. (Ohm's Law: Voltage is Current times Resistance. If the resistance of the conductor is zero, then the voltage across the conductor must also be zero - it does not matter what the current is.)
How a bucking voltage acts?
bucking voltage is a voltage which is of opposite polarity to the voltage it acts .
Dc and ac analysis of Differential amplifier?
DC Analysis: For this analysis, frequency is made zero and the voltage of the source is increased in small steps from 0V.And the output voltage is plotted. So, finally we get a Vout vs Vin curve. AC Analysis: In this analysis, we choose an AC source. We keep the Offset voltage = 0V, AC voltage or small signal voltage = 2V (You can take any voltage you wish and it doesnt matter). So, to plot the ac response or frequency response of the circuit, increase the frequency in steps and note the output voltage. from this analysis , we can find the gain of the circuit over frequency.
What do you understand by stabilizer explain its uses?
A Stabilizer maintains the voltage across a load constant no matter how high the current goes.It can be used to maintain the voltage across a load constant no matter the variation in supply voltage and also it can be used to maintain the supply voltage constant no matter the variation in load.
Does centre tap transformer convert ac voltage to ac voltage?
Yes. Transformers convert power by stepping up or down voltage. It doesn't matter what tap configuration they have.
How can calculate resistance for negative dc voltage?
Resistance calculations are the same no matter what the polarity of applied voltage. R=E/I Resistance (in ohms) = Voltage (in volts) divided by Current (in amperes)
Does it matter if the voltage leads the current or the current leads the voltage?
Yes. If voltage leads the current, the impedance is inductive (this would be the case if the load is a motor). If current leads the voltage, the impedance is capacitive (this would be the case for a CFL light bulb).
Utility voltage is 115 volts at a frequency of 60 Hz what is the peak to peak?
A: Take 115 volts and multiply by 2.82. The frequency does not matter but he voltage does
Is the alternator the same as a voltage regulator the same on a 98 ford contour?
The voltage regulator is built into the alternator on all Contours, no matter what year or engine.
How much voltage does a fan use in one minute?
Usually the voltage remains the same no matter what time frame that it is used in. What ever the manufacturer states that the working voltage is, that should be the voltage that is applied to the equipment. From the time the fan starts up until the fan shuts down the voltage value does not appreciably change.
What ismean by current source?
A current source produces a constant current no matter the variation in voltage.
How is the current affected in a series circuit?
A: In series circuit the current remains the same no matter how many components are in series. just the voltage will change to reflect different voltage drops for each.
How do you change operating voltage of metal halide lamp from 240 to 120?
You would need to use a transformer to step down the voltage from 240V to 120V. Make sure to select a transformer that is rated for the power consumption of the metal halide lamp and have a qualified electrician perform the installation to ensure safety and proper operation.
Is ohm's law in Vrms or Vpp?
It doesn't matter as long as you measure both voltage and current in same units.
How many kw in 3hp in 415volts?
3 HP is 3x746 watts, it doesn't matter about the voltage, it could be anything.
