    \$\begingroup\$ Some current will flow from base to emitter. \$\endgroup\$ – mkeith Oct 5 '17 at 2:33

    \$\begingroup\$ The base/emitter junction will act like a diode, and conduct current. \$\endgroup\$ – Peter Bennett Oct 5 '17 at 2:53
  • \$\begingroup\$ If you do not limit the current, you will let all the magic smoke out. Just like ballbearings go up in smoke. \$\endgroup\$ – analogsystemsrf Oct 5 '17 at 3:13
