SHOPEE COMPRAR AGORAYou might ask why transistor like 2N2222 is used here. Bipolar transistor like 2N2222 is current amplifying device which amplifies the base current by its current gain to get amplified collector current.As we have mentioned earlier, switches are open and closed diagonally in an H-bridge circuit, but these actions can’t go on s
