Answer Wiki. To reverse the current, you need to reverse the voltage. It will be more easier if you think in terms of voltage. Now, this can be achieved in many ways. It depends on what is your power requirement. If your current requirement is less than 1A, you can use a motor driver IC like L293D.
Figure 4: The reverse-biased junction in an npn transistor. The second pn-junction (base-to-collector), or reverse-biased junction as it is called (figure 4), blocks the majority current carriers from crossing the junction.However, there is a very small current, that does pass through this junction. This current is called minority current, or reverse current.ince electrons are the majority carriers in the n-material, they will move through the n-material emitter to the emitter-base junction. With this junction forward biased, electrons continue on into the base region. Once the electrons are in the base, which is a p-type material, they become minority carriers.
