Who made the beam of electrons in vacuum tube?
This beam of electrons is emited by the cathode under voltage difference.
What is voltage and state its unites?
Voltage is a measure of relative concentrations of electrons. The units is volts.
WHAT IS An excessive amount of electrons at one end of a conductor and deficiency at the other?
Voltage <><><><><> Actually, an excess or deficit of electrons is called a charge. It is measured in coulombs. Voltage is joules per coulomb, meaning that voltage is energy per charge.
What measure of electrical energy transfers by electrons in a circuit?
Voltage
What is the electrical pressure that causes electrons to flow?
voltage, breh
Is velocity of electrons increase by increasing voltage?
Depends on what is between the potential difference (ie, the voltage). If it's an evaculated tube, and the electrons are travelling between the anode and the cathode without much interference, then then a higher voltage will mean that the electrons arrive with more kinetic energy -- ie, increased velocity. However, if there's a wire between the two voltages, then the drift velocity of the electrons (which is pretty slow to begin with) does not increase, but only the number of electrons that are drifting.
What must occur before the current flows through a circuit?
As current is the rate of flow of electric chargesAs I=Q/tso,there must be free electrons for the flow of electric current in a circuit.Then when voltage is applied at the terminals of circuit the free electrons acquire an average velocity called as drift velocity in the opposite direction to that of electric field (-E).Now the free electrons modify there random motion and a steady current begin to flow in a circuit.
How do humans acquire voltage in their bodies?
Every organism, including humans, is made up of atoms which are made of protons, neutrons, and electrons. When an atom becomes positively or negatively charged, the flow of electrons between the two is actually electricity.
How do electrons flow in an electric in terms of voltage difference?
Electrons are negatively charged particles. When a voltage difference exists, electrons are repelled from the more negative (or less positive) voltage toward the more positive voltage. If they are in a material which allows conduction of electricity, then the electrons will flow toward the more positive voltage.
How do electrons in an electric circuit in terms of voltage difference?
Electrons are negatively charged particles. When a voltage difference exists, electrons are repelled from the more negative (or less positive) voltage toward the more positive voltage. If they are in a material which allows conduction of electricity, then the electrons will flow toward the more positive voltage.

What happens to the distance electrons travel when voltage is changed?
Electrons will travel farther distances at a lower voltage.
How do you open Solenoid?
Usually by applying a voltage to it.
What is the basic mechanism responsible for emission of visible radiation in an LED?
by applying a voltage across the boundary of two semi-conductors electrons are forces to travel across the boundary. This boundary has a voltage drop and the electrons are required to lose a discrete amount of energy in crossing it. In the case of the light emitting diode, it is a energy in the range of visible light.
Voltage is the pressure used to push electrons or what through a resistance?
voltage
Current and voltage?
The current is the flow of electrons The voltage is the push the power source gives to the electrons to make the current faster. The flow of electrons is electricity HI!! By the way I am amazing! Trust me.
How do they get the electrons moving?
to actually get the electrons moving there needs to be an electric potential better known as voltage. the voltage allows the electrons to be attracted towards, repelled from in one direction across cables
