I'm trying to learn a bit more about forward voltage and Ohm's law but I'm not sure how to wire this circuit.
One 4.5 DC motor (Operating Volts: 1.5- 4.5V, Nominal Volts: 4.5V, Current (no load): 0.25A)
Three 5mm LEDs (IF Typical (mA)20, IF Max Continuous (mA)50, VF Typical (V)2.1) -
One 3 - 12VDC Switchmode Plugpack (Output voltage: 3, 4.5, 5, 6, 7.5, 9, Output current: 1000mA (max))
Do I use the power at 4.5V and run the motor and the LEDs in parallel?
Do I need resistors on the LEDs?
