The cathode is the positive end of the battery? True or False
True
What would happen to your stomach if you swallowed a coin battery?
It would dissolve. DO NOT EAT!
What is the component of an electric circuit that slows down electric current?
Resistor
This shape of battery is usually used in low power electronic like wrist watches.
Coin
A vertebrate that lives its entire life underwater and uses gills to breathe.
Fish
What is C-Rate?
How quickly a battery can charge?
The names for the two terminals of a battery.
anode and cathode
The reason batterie should be recycled
toxic chemicals are bad for the environment
In order for electricity to flow, the circuit must be
closed
a primary battery used in most flashlights and common household electronics
AA
This aquatic animal is the 10th fastest creature alive according to the wikipedia page for fastest animals.
Black Marlin
How long will it take to have a 4C battery fully charge?
15 minutes
This plays a part in creating a flow of electrons from the negative end of the battery, to the positive end of the battery
electrolytes
why is lithium such an explosive elecement, like sodium or potassium
only one electron in the outer shell of the atom, highly reactive
This is the electric term used to describe how badly charges are pushed through a wire
voltage
This is the primary kind of batteries used in cars
lead acid batteries
This animal can produce electrical voltages from their body that can reach 860 volts according to wikipedia.
Electric Eel
What is the C-rate for a battery that takes 2 hours to charge?

Connecting multiple cells together leading to larger surface area connection between each part of a battery cell results in...
more power!
the worst metal that is super toxic and used in old gasoline and some batteries
lead
series circuit
This battery uses liquid containers for its anode and cathode
flow/vanadium battery

How much energy is in a battery that has 9V and 7.5 Ah of charge?
67.5 joules of energy
What happens when a battery is recharged?
metals are Undissolved so the reaction can occur again.
If a battery above 1.5 Volts is swallowed, it can result in this reaction which rips apart the water molecules in their bodies.
Hydrolysis
this is a circuit where you can disconnect one light bulb, and the others stay on. It gives charges multiple paths to travel.
parallel
these batteries can be cut into any shapes
pouch battery
