,What actually produces electric current? - ** VERIFIED ANSWERS **✔✔The transfer of
energy from valence electron to valance electron as a result of applied charges is what
actually produces electric current
How does the speed of electric current compared to that of electron travel? - ** VERIFIED
ANSWERS **✔✔The affective speed of electric current is 186, 00 0 mi./s is much faster
than the actual speed of electron travel
What is the basic measurement unit of electron current? - ** VERIFIED ANSWERS
**✔✔The ampere is the basic measurement unit for electron current
Define electromotive force (EMF) - ** VERIFIED ANSWERS **✔✔EMF is the electrical
force that motivates electrons to move in a wire
What does the term potential difference mean? - ** VERIFIED ANSWERS **✔✔Potential
difference is the algebraic difference between the electrical individual potential's of two
points
