Am doing a project that has to use a transistor, as a switch, actually switching a 12V relay switch, that is actually responsible for switching another circuit, but as a result the relay doesn't switch ON, but makes noise continuously, in this clearly certain that the voltage across the relay is around 5V, can this be the cause of the noise, and by the way what can i do to solve it, am not aware of transistors with large large current gain, since the base current can't be easily altered and its very small, guys can you help me out here...
