To reverse the direction of current, reverse the voltage. A common circuit to do this under digital control is an H-bridge which consists of 4 transistors, a positve supply input and a negative input supply. and two ouptuts - the polarity of which is swapped by an input control line.
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.
