In the motor circuit example, what voltage does the battery provide to the motor?

The voltage delivered to a DC motor in a simple circuit is basically the supply voltage from the battery, with only small drops from wiring or switches. In this motor circuit example the battery is a 12 V source connected directly to the motor, so the motor receives about 12 volts. That matches the motor’s operating voltage and allows it to run at its intended speed range. Choosing other voltages wouldn’t fit the setup: a 5 V or 9 V supply would be underpower for many standard motors, leading to sluggish performance, while a 15 V supply could exceed the motor’s rating and risk overheating or damage. The diagram’s 12 V labeling is what determines the voltage seen by the motor.
