Units used to measure the rate of electron flow in a circuit:

Ampere (A)

Explanation:

The rate of electron flow in a circuit corresponds to the current in the circuit, defined as:

where Q is the amount of charge that passes through a given point in the circuit in a time interval of t.

The charge Q is measured in Coulombs (C), while the time t is measured in seconds (s), so the unit of measurement of the current is

and this unit is called Ampere, and it is indicated with [A].

no simpler subs form complex ones. synthesise = make

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
