Answers
Answer:
Q1: Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms
Q2: Ampere
The SI unit of current is Ampere.
Q3: Georg Simon Ohm
Abstract: The "it" in the title refers to what is now known as Ohm's law. Georg Simon Ohm (1789-1854) lived at a time when there were no calibrated indicators for electric current. There was no volt or amp; these were established much later by the 1881 International Electrical Congress.
Answer:
a)
Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. The common symbol for current is the uppercase letter I. ... Physicists consider current to flow from relatively positive points to relatively negative points; this is called conventional current or Franklin current.
b)
ampere
Unit of electric current: ampere (A)
The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 ×10−19 when expressed in the unit C, which is equal to A s, where the second is defined in terms of ∆νCs.
