Is a battery a source of current?
A battery is a voltage source, not a current source.
Are batteries secondary sources of energy?
The primary sources of electrical energy can only directly power limited types of electrical devices, such as the incandescent bulbs in flashlights powered by batteries. … These devices are called “secondary sources of electrical energy.” In the American technical literature, they are usually called power supplies (PSs).
Is battery a power source or voltage source?
A battery is considered to be a voltage source because the galvanic activity they use to store and deliver energy has a fixed voltage across it. However, a battery is not an ideal voltage source. All real sources have some built in resistance.
Where is energy stored in a battery?
The energy is stored in the particular compounds that make up the anode, cathode and the electrolyte–for example, zinc, copper, and SO4, respectively.
Is a battery a source of constant voltage or current?
A battery is an example of a real voltage source. Over a reasonable range of currents, the voltage of a battery does not change. A small AA battery producing 1.5v will hold that voltage constant for currents between 0 and say 20ma. At higher currents the voltage may droop down a little, but not too much.
