Hello! I have done some research on transistors because I want to increase my current via increasing the voltage of a circuit in order to offset the increased load. As far as I understand, transistors can amplify (increase) voltage and current, as well as rectify (does this mean it can convert AC to DC?). Is this true that it will increase the current and voltage? And if so, how can I know by how much it will increase it? And if not, what are any other options for increasing voltage and current when a load is placed on a circuit? Thank you!
