FAQs about How much current does the battery have when it runs out of power
How does a battery determine the amount of current thrown?
your battery never determine the amount of current throw to the load, rather the load resistance and operating voltage of the load determine the amount of current. For two or more load resistance (Vs= Vr1+Vr2+Vr3...+Vrn) and each voltage drop (Vr1=IR1, Vr2=IR2,, Vrn=IRn).
What happens if a battery carries a current?
When a battery or power supply sets up a difference in potential between two parts of a wire, an electric field is created and the electrons respond to that field. In a current-carrying conductor, however, the electrons do not all flow in the same direction.
