DQuestion 1 1 pts A common driving source for a DC circuit is a . Question 2 1 pts Electrical energy is stored and used as direct current in batteries as non-corroded material that releases energy during the corrosion process; it is also stored as charge distributed on capacitor plates during the corrosion process;it O True False Question 3 1 pts The process taking place in a battery to produce electrical charge is a corrosive reaction between two dissimilar metals placed in an electrolytic solution. O True False

Explanation / Answer

1) Common driving source for DC circuit is Batteries

2)False

3)True,Energy cannot be created or destroyed, but it can be saved in various forms. One way to store it is in the form of chemical energy in a battery.

4)The Galvanic series is a ranking for materials. When any electrodes are immersed in any electrolytic solution they will undergoes corrosin,the rate of corrosion depends on the electrolyte,the difference in corrosion levels measured as ionizing potentials.

5) In flashlight batteries carbon and zinc electrodes are used
