What is a Battery?
The chemicals in the battery will ultimately reach a state of equilibrium. In this state, the chemicals will no longer have a tendency to react, and as a result, the battery will not generate any more electric current. At this point, the battery is considered "dead." Primary cells must be disposed when the battery is dead.
Calculating Electric Power | Ohm''s Law | Electronics Textbook
Learn the Power Formula. We''ve seen the formula for determining the power in an electric circuit: by multiplying the voltage in "volts" by the current in "amps" we arrive at an answer in "watts." Let''s apply this to a circuit example: How to Use Ohm''s Law to Determine Current. In the above circuit, we know we have a battery voltage of 18 volts and a lamp resistance of 3 Ω.
