Here's what I wrote down in my notes for MAKE ex 5. I haven't memorized it yet, but I am thinking of making flashcards for it. Here are my notes:
-When zinc reacts chemically with an acid, it can liberate electrons
-Electrons want to leave without other electrons joining them (aka mutual repulsion)
-When a wire connects the zinc electrode to another electrode with an shortage of electrons, the electrons move from one atom to the next to go from zinc electrode and run through wire
-more electrons reduce previous ones in the process until zinc-oxide reaction grinds to a halt
-primary battery = a battery ready to generate electricity the second there is a connection between its terminals
-when raw metal in electrodes is used up, the battery dies
-emitting electrons = to send electronics
-Negative electrons flow from positive to negative
- 1 amp = 1 coulomb/second
-coulomb = unit of electrical potential
-1 newton = the force required to accelerate 1 kilogram by 1 meter per sec
-1 joule = a force of newton acting through 1 meter
-chemical reactions inside batteries change pure metals into metallic compounds which enables power
-this process can be reversed
-2 batteries in series deliver twice as much voltage
-2 batteries in parallel deliver twice as much current
Also, does the potential difference determine how long the electricity will flow until both sides of the battery are equal? I'm just asking because I happened to think of it writing this.
I'm going to make flash cards out of these so I wanted to know if they were okay. Thanks for the replies.
