* Some voltage powers electrical devices
  - small electrical devices
  - pushes electric charge
* are compared to the ground to measure voltage.
* better-known quantity than electric field.
* can exist only where there current path
  - set off most receptors
* causes current to flow, while resistance and impedance oppose it
* comes from various sources.
* concept that is related to potential energy.
* controls the balance between uptake and release.
* depends on battery types
  - the light's wavelength and intensity
* describes how much energy the electrons carry.
* drop The loss of electrical pressure caused by resistance in a circuit.
* drops when a load is placed on the power system, or when the battery discharges.
* energizes phosphor atoms.
* expresses the amount of energy expended per amount of electric charge.
* gated ion channels are critically important in synaptic function.
* has functions
  - origins
  - to do with potential energy
* is an across variable
  - electrical phenomenon
  - energy measure, the energy carried by one coulomb of electrical charge
  - analogous to water pressure
* is applied at both ends of the tube to generate an electric current
  - between two electrodes in a probe immersed in the sample water
* is applied to certain areas, causing the crystal to turn dark
  - which causes the crystal to turn dark
  - approximately proportional to speed
  - associated with electrostatic fields in space
  - between two points in a circuit
  - determined by the number of cells in the fuel stack
  - due to a charge difference
* is electrical pressure or force
  - energy per unit charge or electric field times distance
  - equal to current multiplied by resistance
  - indicated by a mechanical displacement of a pointer against a scale
* is like altitude
  - an electrical pressure that pushes the coulombs through the circuit
  - the height difference between two ends of a river
  - measured by putting the galvanometer across the voltage drop to be measured
* is measured in units called volts and current is measured in units of amps
  - volts , current is measured in amps and resistance is measured in ohms
* is measured in volts, V for short
  - millivolts, microvolts and kilovolts
  - on an interval scale , which means that only differences can be measured
  - to estimate the amount of current thatcould flow through an animal
  - only one facet of electricity
* is produced by a chemical reaction
  - proportional to current - over a limited range
  - required to create a current
  - similar to water pressure
  - something like electrical pressure
  - sort of like electrical pressure
  - the amount of pressure pushing the electricity through the wires
* is the difference in charge between two points
  - electrical charge between any two points
  - electric force that causes current in a conductor
* is the electrical equivalent of water pressure
  - potential energy and is measured in volts
  - energy per electric charge, it is measured in volts per coulomb
  - force that causes the current to flow
  - measure of electric potential
  - most frequently measured electrical quantity
* is the parameter of electricity which causes current to flow when a circuit is completed
  - that is the most used, and the most misunderstood
* is the potential energy per unit charge for a charge in an electrical force field
  - to move
  - power a battery can deliver
  - pressure pushing the electrons through the wires, it is measured in volts
* is the pressure that causes the electrons want to flow
  - makes electricity flow
* is the pressure that pushes electrical current through a wire
  - electricity along, like water though a hose
  - same across all resistors in parallel
  - work done per charge
  - therefore a direct measure of nerve conduction threshold
* measure of potential energy contained in the battery and is measured in volts
  - the electrical energy of a circuit
* occur at nodes.
* physical variable that can be thought of in different ways.
* plays a role in the mobility of proteins on a gel.
* produces current
* reads low when vacuum is high, and increases as vacuum drops.
* relative quantity.
* represents the work involved in the transfer of electric charge from one point to another.
* results in electric energy
* specific measure of potential energy that is always relative between two points.
* unit of electrical current.
* varies according to the number of individual cells making up a stack.
+ Battery, What is inside a battery (the chemistry)
  * Connecting the positive of one cell to the positive of the other, and the negative to the negative is called connecting them 'in parallel'. The voltage stays the same, but the current is added together. Voltage is the pressure pushing the electrons through the wires, it is measured in volts. Current is how many electrons can go at once, it is measured in amps.
+ Ground: Geography
  * It is the dirt, soil and rock that we walk on. Ground in electrical language is the electrical charge of the earth. Voltages are compared to the ground to measure voltage.
