How you would use the water flow to demonstrate a low-voltage electric current?
In a water system, the "voltage" is the water pressure, the flow rate is the "current", and the pipe size is the "resistance". Low-voltage electrical current is equivalent to low-pressure water.
How is the electron flow different from conventional current?
The conventional current direction is the direction in which a positive charge would move. Since electrons are negatively charged, the electrons move (in average) in the opposite direction.AnswerBefore the structure of the atom was understood, scientists such as Benjamin Franklin believed that an electric current was a flow of some sort of mysterious 'fluid' that moved from an area of high pressure to an area of low pressure. The high pressure was considered to be 'positive' pressure and the low pressure was considered to be 'negative pressure'. So, for many years, current was believed to travel from positive to negative, but it had nothing to do with 'a flow of positive charge carriers' because no-one then knew about 'charge carriers'.Even though we now know that (in metallic conductors, anyway) that current is a flow of free electrons from negative to positive, for some weird reason many textbooks still show current as flowing from positive to negative! To differentiate between the two current directions, we use the terms 'electron flow', and 'conventional (or 'Franklinian') flow'.
What is the relationship between potential difference and direction of flow of current in an electric circuit?
Electric current always flows from high potential to low potential. This creates the flow of electric current in an electric circuit.AnswerIn a metal conductor, current is defined as a drift of free electrons. As electrons are negatively charged, this means that current drifts along a conductor from a negative potential to a positive potential.However....Current direction is often defined as a drift from a positive potential to a negative potential. This is termed 'conventional flow', and dates back to when scientists, such as Benjamin Franklin, believed that current was some sort of fluid that flowed from a higher pressure ('positive' pressure) to a lower pressure ('negative' pressure). Although incorrect, conventional flow is still widely-used today in many textbooks.
Flow of water and electric current is compared to?
Voltage is what they are compared to.
What are the two things that make electricity flow?
You have to have a charged particle which is free to move, and an electromotive force for a current to flow.
Voltage is pressure and current is flow what opposes flow?
Reverse current.
How does push to make switch work?
Push-To-Make switch is a switch in which pressure is applied to the switch for it to let the electricl current flow through.
What pressure or force that causes current flow through a conductor is caleed?
The pressure or force causing current to flow through a conductor is called voltage.
What is voltage and current?
Current is defined as the rate of flow of charge through a body. ie, I = Q / T Voltage is the amount of Pressure needed to make the charge flow through the body. ie, V = J / Q A; current flow is not related to time if the EMF is constant the current flow will be constant. A1: current is electrons flow caused by the presence of EMF. A2: voltage is the EMF force necessary to make current or electrons to flow.
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 do you understand by technical current direction?
Current in metal conductors is normally termed either 'electron flow' or 'conventional flow'. I'm not aware of the term, 'technical current'.'Electron flow' assumes that current is a flow of free electrons through the conductor, from a negative potential to positive potential.'Conventional flow' (also known as 'Franklinian flow', after Benjamin Franklin) predates what we know about the atom, and was based on the assumption, by scientists such as Franklin, that current was a flow of some mysterious 'fluid' from a higher pressure ('positive' pressure) to a lower pressure ('negative' pressure).Some textbooks assume 'electron flow', whereas most assume (for no accountable reason!) 'conventional flow'. At least one textbook I know of has been published in two versions: an 'electron flow version' and a 'conventional flow version'!
Why are electron and current flow in opposite directions?
It's basically an accident. Current flow was defined before science had figured out electron flow.AnswerBefore the structure of the atom was understood, scientists such as Benjamin Franklin believed that an electric current was a flow of some sort of mysterious 'fluid' that moved from an area of high pressure to an area of low pressure. The high pressure was considered to be 'positive' pressure and the low pressure was considered to be 'negative pressure'. So, for many years, current was believed to travel from positive to negative.Even though we now know that ( in metallic conductors, anyway) that current is a flow of free electrons from negative to positive, for some weird reason many textbooks still show current as flowing from positive to negative!

How you would use the water flow to demonstrate a low-voltage electric current?
In a water system, the "voltage" is the water pressure, the flow rate is the "current", and the pipe size is the "resistance". Low-voltage electrical current is equivalent to low-pressure water.
What do you call the measure of electrical pressure?
Electrical pressure is the difference in electrical potential between two points with or without current flow. Without current flow it known as an EMF (electro motive force E) with current flow it is described as a potential difference (pd V). Both are measured in volts (symbol V).
Is a ohmmeter a pressure gauge?
No. An Ohmmeter measures electrical resistance to the flow of current.
How much current is need for 12 VDC to flow through water?
First thing voltage does not flow current does. Voltage is the potential or pressure needed to make the current flow. Current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. To make the current flow you have to adjust the resistance of the circuit and that would be the water in this case. Salt added to water will make the water conductive so the resistance can be adjusted thereby making the current rise or fall depending on the water solution's resistive properties. The equation that you should consider using is Amps = Volts/Resistance.
How is different between voltage and current?
voltage = the electrical "pressure"current = the electrical "movement rate" or "flow rate"
