How long can a 35 mAh battery charge a device that requires a 70 mA current?
30 minutes, right?
30 minutes, right?
mfb said:The voltage has to be considered as well.
Voltage is what makes the charge flow. You couldn't directly charge a battery of higher voltage with one of lower voltage, for example.BillyBobJoeseph said:How so?
BillyBobJoeseph said:Thanks. Follow up question, all other factors aside, a 1000 mAh battery would last 1/2 has long as a 2000 mAh battery right? The device would still act the same way, not like voltage where it requires a certain amount, correct?
A simple battery is a device that converts chemical energy into electrical energy. It consists of one or more electrochemical cells, which are connected in series or parallel to increase the voltage and current output.
A simple battery works by using a chemical reaction between two electrodes (an anode and a cathode) and an electrolyte solution. This creates a flow of electrons from the anode to the cathode, producing an electric current.
The most common types of simple batteries are alkaline batteries, lithium-ion batteries, and lead-acid batteries. Alkaline batteries are typically used in household devices, while lithium-ion batteries are commonly found in electronics such as laptops and smartphones. Lead-acid batteries are used in automotive and industrial applications.
The lifespan of a simple battery depends on factors such as the type of battery, the amount of energy it is required to provide, and the conditions in which it is used. Generally, simple batteries can last anywhere from a few hours to several years.
Simple batteries should be disposed of properly to prevent harm to the environment. You can recycle them at designated recycling centers or drop-off locations. It is important not to throw them in the regular trash as they may release harmful chemicals into the environment.
