In an ammeter, the magnitude of the electric current - that which is measured in amperes - is measured via the magnetic deflection it causes in a needle. Note that this measures the flow of electric charge; it doesn't tell you specifically whether what is moving is electrons.

Actually, it's more accurate to say that the ampere is a unit of the rate of electrical charge flow (one ampere equals one coulomb of charge per second).

What is the unit for measuring the rate of electron flow in a circuit?
Electron flow is known as current. SI unit is Ampere
Rotameter is used for measurement of?
It is used to measure the rate of flow of liquid & glasses
What is rotameter?
A Rotameter is a device that measures the flow rate of liquid or gas in a closed tube. It is occasionally misspelled as "rotometer." It belongs to a class of meters called variable area meters, which measure flow rate by allowing the cross-sectional area the fluid travels through to vary, causing some measurable effect.
Is it true that In Ohms law the variable i represents the rate of flow of charge which is called impedance?
"I" represents the current which is the flow of electric charge. Impedance is the measure of the opposition to the flow of current at a given voltage usually in a.c. circuits.
What is performance ratio of desalination plant?
the ratio of the distillate mass flow rate to the mass flow rate of the steam used
Units are used to measure the rate of an electron flow is called?
Amperes, milliamperes, microamperes, etc.
What is the unit for measuring the rate of electron flow in a circuit?
Electron flow is known as current. SI unit is Ampere
What is cubic feet per minute?
It is an old measure for rate rate of flow.
What is a unit of measuring rate of electron flow in a circuit called?
Electron flow is known as 'current' the unit of current is an amp
What is a measure rate at which heat flows through it?
conductivity. The answer you need is as follows. Heat energy is measured in Calories or Joules or BTU (British thermal units ). Heat flow Rate is measured using the units called Calories per Hour, or BTU/ Hr, or Joules/Hr
What is the purpose of a flow meter?
The purpose of a flow meter is to measure the flow of either air or water. They allow one to measure the total volume of air or liquid flow and the rate of the flow.
Is copper the best conductor?
because copper atom has one electron in outer shell and easy to to energize to flow to other copper atom we now that the rate of flow of electron is current
What do amps measure in a circuit?
Amperage or Amps is a measure of is the flow rate of electrical current that is available.
A weir gauge would be used to measure the?
flow rate of water
What are flow meters used for?
Flow meters are used to measure the linear, nonlinear, mass, or volumetric flow rate of a liquid or gas.
For what can one use a capillary rheometer?
A capillary rheometer is used so that you can measure the rate of blood flow from your capillaries. Also, you can measure the rate of the blood flow inside of it, which can help you tell whether or not you have a broken one.
Applications of orifice meter?
1.to measure the flow rate of gases and fluids
