| (1/1) |
| Camelkos:
hi everybody, i'm reading the art of electronics 2 and i'm stuck at the circuit B to switch the high side of a load returned to ground in the chapter of bipolar transistors, can someone explain it to me please, thank you all !! |

We don't all have that book so give us the source and perhaps we can help. |
| MarkF:
Is this the circuit? |
| bob91343:
If B is the circuit, then driving Q2 with a pulse will turn it on, which in turn provides base current for Q3 and thus energizing the load. |
