Relay driver ransistotr switch ransistotr switching networks logic gates current mirror voltage level indicator dr. B we ve added ammeters to measure the base and collector currents as well as voltmeters to measure the voltage across the transistor and the relay coil. In this situation no collector current flows and the relay coil is de energised.
Here the ground refers to the negative line for an npn and the positive line for a pnp bjt.
The microcontroller provides high or low input signals to npn transistors. Relay driver circuit using pnp bjt. The relay driver circuit using an npn transistor is given below. The microcontroller provides high or low input signals to npn transistors.
