Introduction. Batteries are a collection of one or more cells whose chemical reactions create a flow of electrons in a circuit. All batteries are made up of three basic components: an anode (the ''-'' side), a cathode (the ''+'' side), and some kind of electrolyte (a substance that chemically reacts with the anode and cathode).
Solution. We start by making a circuit diagram, as in Figure (PageIndex{7}), showing the resistors, the current, (I), the battery and the battery arrow.Note that since this is a closed circuit with only one path, the current through the battery, (I), is the same as the current through the two resistors. Figure …

The ground pin on the microcontroller is two things: (1) a voltage reference, and (2) a current return. Voltage Reference: Voltages don''t really exist at single points, voltages are differences between points. This means that to speak sensibly about some single point in a circuit being at a given voltage, it has to be relative to some other point in the circuit.
Many of the circuits are low power for beginners (9V Battery is used). But it is not always the case. Some circuits may require more power and you may deal with high voltages including both AC and DC. The best practice is, Never work with a circuit when power is on.
