Question

what is magnitude..?? what is electric current??

Answer 1

Current, measured in Amperes (A), has the symbol "I" ('eye') and is equal to the charge (Coulombs, C) per unit time (Seconds, s). In other words, it is the number of electrons passing a point per second. 

I = Q/t 

Where Q is charge and t is time

Current is also equal to the potential difference (voltage, V) across a component over the resistance (ohms) of the component

I = V/R

Answer 2

The magnitude is a number that characterizes the relative size of an earthquake. Magnitudeis based on measurement of the maximum motion recorded by a seismograph.

























An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas. ... Electric current is measured using a device called an ammeter.
