What else can I help you with?
How do you calculate the joint resistance in a series circuit with three resistances?
The resistance of a series circuit is simply the sum of the individual resistors.
Does current depends on its resistance?
The current flow in an electrical circuit depends on the applied electromotive force (EMF, measured in volts), and the total resistance along the entire circuit. Rising EMF or dropping resistance cause increased current flow
Can inserting a resistor in a circuit produce an effect similar to a open circuit?
Of course it depends entirely on the ohm's resistance of the resistor. The higher the resistance, the lower the comparison to a short circuit.
Is resistance box connected in series or parallel?
It depends on what you want to accomplish. If you want to decrease the resistance in a circuit, you would place the box in parallel to some other resistor. If you want to increase the resistance in a circuit, you would place the box in series.
What is frequency of dc?
You can say DC voltage has a frequency of zero Hz.Because it is unidirectional in nature (may be positive or negative)
What does a resonators do in a electric circuit?
A resonator is a circuit that responds to a narrow range of frequencies. A typical resonator is a tuned circuit containing an inductor and a capacitor in series or parallel. A series connected tuned circuit has zero impedance at the resonant frequency, while a parallel tuned circuit has infinite impedance at the resonant frequency. The resonant frequency in both cases depends on the inductance times the capacitance: F = 1 / (2.pi.sqrt(LC)) If the inductance is in Henrys and the capacitance in Farads, the answer is in Hz.
What will b the power factor of a series circut when r is made zero?
The power factor never depends on the resistance of a circuit. It depends on the equivalent inductance and capacitance in the circuit, and on the frequency of the power supply, even if the resistance is zero.
How do you calculate the joint resistance in a series circuit with three resistances?
The resistance of a series circuit is simply the sum of the individual resistors.
What is the change in current when frequency changes from 8 khz to 400hz?
That depends on the circuit. For a pure resistive circuit (no inductance and capacitance), the frequency will have no effect on the current.
What is the sound of glass smashing measured in decibels?
It is not so much the volume of the sound as the frequency as well. Sound at the wrong frequency can be played as loud as you like and it will not break the glass. The sound needs to be the same frequency as the resonant frequency of the glass (tap the glass, that note is it's resonant frequency). Once the resonant frequency has been found, it does not take much volume at all, even humans can do it, albeit trained singers (see Mythbusters).
What is the effect of frequency on amplitude?
The relationship between frequency and amplitude depends on the system being analyzed. In some systems, increasing frequency may result in an increase in amplitude (resonance), while in others it may decrease. Generally, higher frequencies can lead to higher amplitudes in resonant systems, while non-resonant systems may have a more complex relationship between frequency and amplitude.
What does a current in a circuit depend on?
current depends on applied voltage and resistance.
Does current depends on its resistance?
The current flow in an electrical circuit depends on the applied electromotive force (EMF, measured in volts), and the total resistance along the entire circuit. Rising EMF or dropping resistance cause increased current flow
If you cut a wire what happend to resistance?
If you are talking about the total resistance in a circuit , it depends on the components in the circuit and the location of the cut.If you are talking about a single wire, the resistance becomes infinite (or close to it) when the wire is cut.
Can inserting a resistor in a circuit produce an effect similar to a open circuit?
Of course it depends entirely on the ohm's resistance of the resistor. The higher the resistance, the lower the comparison to a short circuit.
What does the size of a current depend on?
The size of a current depends on the voltage applied and the resistance of the circuit.
The amount of current that flows in a parallel circuit branch depends on the what?
... the voltage of the power supply and the resistance of that branch alone.
