Spout battery configuration and polarization

Video transcript

so this mock-up was created to sort of show another part of the circuit when we turn the switch here the power switch and see both the motors spin in this direction they're pulling power from the battery and it's flowing through the motors causing it to spin this way so you can see that the ground wire from the battery here is connected to the blue wire which goes to the motors and then that goes to a switch and that's connected back to the the positive side on on the battery here so that's causing the motors to spin in this direction when they're wired like that notice the positive wire here is tied off we don't need the positive wire because we're using this yellow wire to connect to the batteries and we just need this one battery to power these two motors because one battery is 1.5 volts and that's enough to get the motors to turn and so we're going to use this battery to make the motors turn backwards you can see when we turn it on the motor spin backwards now in this configuration what we've done is we've created a mock up again and we want to be able to make the motors again spin forward and backwards so this this setup the motors are spinning forwards so you can see they're going like this they're going forward and the batteries on the other side and we're connected to the positive wire instead of the negative wire and again the negative wires being taken care of because this wire is coming through here so what we've done is we've changed the orientation of the battery and so the power is flowing the other direction causing the motors to go forward so if you reverse the flow of electricity you can change the direction of the motor movement
