What else can I help you with?
If voltage is increased in a circuit what happens to current series and parallel respectively?
In this case current flows from a high voltage to a lower voltage in a circuit.
An increase in resistance in a circuit will cause?
In a simple circuit, lowering the voltage will not cause the resistance to do anything. Lowering the voltage will, however, cause the current to also lower.This ignores temperature coefficient. If there is substantial power involved, a typical bulb, for instance, will grow cooler and its resistance will decrease when you lower the voltage, but that is usually a small effect.
When testing a power transformer with an ohmmeter which winding should have the largest ohmic value?
The higher-voltage winding has more turns (therefore its conductor will be longer) than the lower-voltage winding and, because it will carry less current, its conductors will have a lower cross-sectional area. Consequently, the higher-voltage winding will have a higher resistance than the lower-voltage winding.
What happens inside a voltmeter when you switch it from a lower to a higher voltage range?
When you switch a voltmeter from a lower to a higher voltage range, an additional resistor is added in series with the meter, increasing the voltage necessary to create the same voltage drop across or current flow through the actual meter movement.
How many amperes of current run through 440volts?
Depends on the rating of the source. For the same electrical load, a higher voltage will require lower current, but there's no specific current associated with 440V.
How is voltage created in an electrical circuit?
Voltage is created in an electrical circuit through the movement of electrons from a higher potential to a lower potential, which generates a difference in electrical charge. This difference in charge, known as voltage, creates the force that drives the flow of electricity through the circuit.
What creates voltage in an electrical circuit?
Voltage in an electrical circuit is created by the difference in electric potential between two points, which causes the flow of electrons from a higher potential to a lower potential, generating an electrical current.
How do resistors lower voltage in an electrical circuit?
Resistors lower voltage in an electrical circuit by impeding the flow of electric current, which causes a drop in voltage across the resistor. This drop in voltage helps regulate the overall voltage in the circuit and control the amount of current flowing through it.
What is the force that causes electrons to move in an electrical circuit?
The force that causes electrons to move in an electrical circuit is called voltage. Voltage is the difference in electric potential between two points in a circuit, which creates an electric field that pushes the electrons to flow from the higher potential to the lower potential.
When a circuit is inductive the current has what voltage?
This doesn't make sense, "current" is "amperage" so the higher the voltage the lower the amperage, and the lower the voltage the higher the amperage.
What force pushes electrical current through wires and conductors?
Voltage is the force that pushes electrical current through wires and conductors. It creates an electrical pressure that drives the flow of electrons from areas of higher voltage to areas of lower voltage. This difference in voltage is what causes the electrical current to move through the circuit.
Why do electrical power companies transform higher voltage to lower voltage for residential and commercial properties?
Because the higher voltage would be dangerous domestically.
What direction do the electrical charges flow?
Electrical charges flow from areas of higher potential (voltage) to areas of lower potential. This means that they flow from the positive terminal of a battery to the negative terminal in a closed circuit.
Is it true that electrical current flows from a state of rest to a high pressure state?
No, it is not true. An electrical current (which is a flow of electrons) can only flow from a higher pressure state (higher voltage) to a lower pressure state (lower voltage).
What is the force that pushes electricity around a circuit called?
The force that pushes electricity around a circuit is called voltage. Voltage is the potential difference between two points in a circuit, which causes the electric charges to flow from higher voltage to lower voltage.
Electrons flow from areas of higher to lower voltage or from areas of lower to higher voltage?
Electronsflow from areas of lower to higher voltage, while Current flow from areas higher to lower voltage.
Why would one electrical outlet be lower voltage than all the others?
because the circuit has to many outlets on it
