You are getting ready to power another student's electrical circuit in this class, but you are not sure of the voltage necessary to use. students in this class should always consult the instructor or the other students who contributed to it. Depending on what it accomplishes and how it is made, the design can need a different voltage.
As a precaution against receiving an electric shock, make sure the circuit is inactive before you start working on it. Cut off the power supply.
You can also make use of a voltage regulator.
Regardless of changes in the input voltage or load conditions, a voltage regulator is a circuit that generates and maintains a set output voltage. The voltages from a power source are maintained by voltage regulators (VRs) in a range that is acceptable with the other circuit boards.
