Does the speed of a split phase motor changes appreciably with a change in the applied voltage?
The speed of a split-phase motor is directly proportional to the frequency of the power supply, not the voltage. As long as the frequency remains constant, the speed of the motor will remain relatively stable regardless of minor fluctuations in voltage within normal operating limits.

How does current change across a resistor?
Current changes across a resistor in direct proportion to the voltage applied. This relationship is described by Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), or I V/R.
How capacitor opposes the change in current?
as a voltage is applied across a capacitor charges accumulate on the plates.due to accumulation of charges,electric field between the plates develop in the direction opposite to the applied field.this field give rise to the potential across the plates.if the plates get completely charged due to the applied voltage i.e if the whole of the charge q=c(capacitance of the capacitors)xv(voltage applied) develops on the plates,then the applied voltage wiil be opposed to an extent that no further charges will induce on it.But in practice,it takes very long time for the capacitor to get completely charged due to the applied voltage..............now coming to ac circuits,having capacitor.......if the frequency of ac applied voltage is less then the voltage will change slowly.due to this at each instant large amount of charge will develop on the plates causing large opposition.vice versa to high frequency applied voltage.
How does the voltage across a capacitor change over time when a current is flowing through it?
When a current flows through a capacitor, the voltage across it increases or decreases depending on the rate of change of the current. If the current is constant, the voltage remains steady. If the current changes rapidly, the voltage across the capacitor changes quickly as well.
How can current through material change?
Current through a material can change by varying the voltage applied across the material, altering the resistance of the material, or modifying the temperature of the material. These changes can affect the flow of electrons through the material and, consequently, the current passing through it.
How can the current through material changes?
The current through a material can change by altering the voltage applied across it, changing the resistance of the material, or adjusting the temperature of the material. These factors can influence the flow of electrons through the material, leading to variations in current.
Will the resistance of a copper conductor decrease with an increase in the applied voltage?
If all environmental conditions remain constant then the resistance will not change appreciably with applied voltage, but the current will increase. An increase in current will raise the temperature of the conductor which will increase the resistance somewhat.
What is edge speed in electronics?
A voltage is applied to a signal line. The voltage of the line changes gradually from 0 to +V. The "edge speed" is the rate of change of voltage of the line. A voltage is applied to a signal line. The voltage of the line changes gradually from 0 to +V. The "edge speed" is the rate of change of voltage of the line.
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.
Define the term regulation as applied to dc power supply?
change in load voltage or output voltage changes in load current
Does the speed of a split phase motor change apporeclably with a change in the applied voltage?
no
How does current change across a resistor?
Current changes across a resistor in direct proportion to the voltage applied. This relationship is described by Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R), or I V/R.
How does the voltage applied to a circuit affect the current flowing through the wire?
Voltage is equal to the Current multiplied by the Resistance.Without changing the resistance, increasing the applied voltage in a circuit will increase current flow. There is a simple, direct relationship between voltage and current. Double the voltage, twice the current will flow. Triple the voltage, and the current will triple. As voltage (E) equals current (I) times resistance (R), when resistance is fixed, what happens to voltage will happen to current.
Is the resistance of a resistor the same as voltage changes?
Yes and no. As voltage changes, current changes, causing power to change, with the end result that temperature changes. Most resistors have a small temperature coefficient, so their resistance will change slightly as the voltage changes.
How capacitor opposes the change in current?

What happens to the applied voltage when a change in circuit resistance occurs?
When a dc supply is connected to a resistor, current flows. The current in amps is equal to the supply voltage divided by the resistance in ohms. The power used is the voltage times the current, and that appears as heat in the resistor, which might become hot to touch.
What does a fixed pully change?
It changes the direction of an applied force.
What is the influence of gate voltage on drain source breakdown voltage in mos transistors?
Drain-to-source breakdown voltage (BVdss) should not change appreciably until the gate-to-source voltage (Vgs) approaches the device's threshold voltage (Vth). In that case, the drain to source voltage becomes the product of the drain-to-source current (Ids) and the device's on-state resistance (Rds-on) at the given Vgs.
