Why you need to connect resistor in series for the practical voltage source?
A resistor is connected in series with a practical voltage source in order to determine the current produced by the source.
A series RC circuit will have a phase shift between 0 and 90 degrees?
If there are only a resistor and a capacitor in the circuit, then the phase shift will indeed be between 0 and 90 degrees. When the resistor and capacitor are in series, the phase shift will be negative when the capacitor is connected to a source voltage and the resistor is the load. The phase shift will be positive when the resistor is connected to the source. The lower the values of R and C, the higher the frequency bandwidth.With the resistor and capacitor connected in series and the two parts connected to a current source, the phase shift will be negative. At high frequencies, the output voltages is lower, and the circuit appears as a very low impedance. At low frequencies, the circuit looks more like a resistor. Again, the phase shift will be between 0 and 90 degrees.CommentThe correct term is phase angle, not 'phase shift'. By definition, the phase angle is the angle by which the load current leads or lags the supply voltage. For an RC circuit, the current leads the voltage, so the phase angle is a leading phase angle.
How does a inductor or capacitor returns power to circuit?
A: Current flow only if there is a return path to the source it does not matter what it is connected to. What leaves at one end of the source will be identical to the return in current
How much current flows through a 5k resistor connected to a 20 volt source?
Use the equation V = I * R 20 = I * 5000 I = 20 / 5000 I = 0.004 Amps The answer to your question is 4 mA of current will flow through the resistor.
What happens when closing and breaking an inductive circuit?
When you close an inductive circuit, since an inductor resists a change in current, the initial reaction of the load is to look like a high resistance. As current builds, the resistance falls. With a theoretical source and inductor, current would eventually reach infinity, that is after infinite time, but practical sources and inductors will reach a plateau current. When you open an inductive circuit, again, since an inductor resists a change in current, the inductor attempts to maintain that current, but there is no conductivity for that current so, the inductor presents a high voltage spike in the reverse direction it was initially "charged" with. With a theoretical inductor, and theoretical infinite impedance, the voltage spike would be infinite. Again, practical inductors have a maximum voltage spike, but this spike can still be quite high, even thousands of volts, which can damage the circuit, so it is important to maintain a conduction path for the collapsing field, often a diode, or a resistor/capacitor filter.
What circumstances is it possible for the rms current drawn from a certain source to have the same magnitude when an inductance is connected in series with a given impedance?
The same as what? when an inductor is connected in series with a resistor and a current passed through them, the voltages across the resistor and inductor are equal when the reactance is equal to the resistance: 2.pi.f.L = R
Why a inductor is used in series before diode instead of resistor?
An inductor will supply better current source.
Can a transistor can act like resistor capacitor inductor?
A transistor acts like a resistor when Gate is connected to Source.
Why you need to connect resistor in series for the practical voltage source?
A resistor is connected in series with a practical voltage source in order to determine the current produced by the source.
What is driven RL circuit?
A driven RL circuit is a circuit that contains a resistor (R) and an inductor (L) connected in series with an external source of alternating current (AC) or voltage. The external source provides energy to the circuit, driving the current through the inductor and resistor. This circuit can exhibit interesting behavior such as resonance and phase shifts due to the interplay between the inductive and resistive components.
What are the differences between a parallel circuit and a series circuit?
in parallel circuit passive components such as resistor capacitor and inductor are connected in such away tht all components positive sided terminals are connected together and similarly negative sided terminals. and then positive terminal of the source is connected to positive side and vice versa.while in case of series circuit negative terminal of first component is connected to the positive terminal of the second component and so on and then source is connected
How will be the outputs across the inductor and resistor if you keep the frequency of the input signal very low?
For a low frequency source, the voltage across the inductor tends to zero because its impedance is proportionnal to source frequency, whereas the voltage across the resistor tends to the voltage source value.
Why resistors are connected in series with the voltage source and in parallel with current source?
a voltage source has very less(negligible)resistance.thus is considered as a short.if connected in parallel to a resistor will draw all the current acting as a short.thus is always connected in series of a resistor.where as a current source has tremendous resistance(infinity).thus if connected in series will be conidered as an open branch and no current will flow through it other than the source current.
A 5 ohm resistor a 10 ohm resistor and a 15 ohm resistor are connected in series to a 120 volt power source. What is the amount of current flowing between the 5 ohm resistor and the 10 ohm resistor?
The current would be about 20 volts.
What is the resistor of 18 ohms when connected to a 9v battery?
Even though it is connected to a 9 volt source, it is still a resistor.
A 5 ohm resistor a 20 ohm resistor and a 25 ohm resistor are all connected in series to a 100 volt power source The current running through the circuit is?
E/R=I. 100/50=2 amps.
Does a transformer draw a lot of current when first connected to a source?
Yes it does as it is an Inductor and an Inductor needs to build up a magnetic field. It is called INRUSH current.
