What decreases the flow of electrical charges through a circuit?
Answers
The SI unit of electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. The ampere (symbol: A) is an SI base unit[5]:15 Electric current is measured using a device called an ammeter.[2]:788
Electric currents cause Joule heating, which creates light in incandescent light bulbs. They also create magnetic fields, which are used in motors, generators, inductors, and transformers.
The moving charged particles in an electric current are called charge carriers. In metals, one or more electrons from each atom are loosely bound to the atom, and can move freely about within the metal. These conduction electrons are the charge carriers in metal conductors.
hope it helps you pls mark me as brainlist answer I will help u whenever u need help I m a teacher and the answer is correct
