amt 125

a unit of power that describes the rate of power flow per second.

watt

helps determine the energy needed to perform a task or generate heat

wattage

are the unit of measure for electrical voltage

volts

is the potential pressure that pushes a given electrical current through a connection or conductor

electromotive force

are an important measure for understanding compatibility between power sources and devices

volts

the main sources of voltage (3):

batteries
solar cells
generators

a rechargeable battery that uses lithium and a polymer electrolyte

lithium-ion polymer battery

general purpose batteries

carbon zinc batteries

affordable and widely available

carbon zinc batteries

commonly used in low-drain devices such as remote controls, wall clocks, and basic electronic gadgets

carbon zinc batteries

involve usage in smoke alarms, portable transmitters, scanners, digital voltmeters, door locks, remote controls and laser pointers.

alkaline batteries

a type of rechargeable lithium-ion battery that uses lithium iron phosphate as its cathode material.

lithium iron phosphate batteries

are known for their long life, safety, and performance in extreme temperatures

lithium iron phosphate batteries

are safer than other lithium-ion batteries and are less likely to explode and less likely to overheat

lithium iron phosphate batteries
