| Apr 17, 2017 at 17:17 | comment | added | jonk | Look at where your load, the \$1\:\textrm{k}\Omega\$ resistor, is connected. Ground, right? So, knowing that the load only has direct access to ground, can you tell which BJT will be ON when \$V_{bb}\$ is positive, is negative, and is zero (relative to ground)? I think this is a case where first looking at the load helps a lot more than getting mired in worrying over the rest, too early. | |
