Why npn-transistors are preferred over pnp transistors?
1
Leakage current in NPN-transistors is less than pnp-transistors.
2
Mobility of majority carrier in npn-transistors is greater than the mobility of majority carriers in pnp-transistors.
3
Bias voltage required in npn is less than in pnp-transistors.
4
Bias voltage required in npn is greater than in pnp-transistors.
5
None of these
