Circuits at high voltage show too fast current/fire when the shouldn't #1010

Discussed with @samreid on Zoom. For https://github.com/phetsims/qa/issues/1170. Hard to always get consistent behavior, but I am often seeing the high powered battery, switch, and high ohm bulb out of the box make a high current circuit that is on fire. On the published sim, current in this situation should be 1, but it much higher in the bugged state. Best steps I've found:

  1. Sim loads with all noise on
  2. Build a circuit That goes High Volt battery, wire, switch, wire, high ohm bulb, wire
  3. Flip switch
  4. Turn off circuit noise
  5. Disconect wire from bulb on switch side
  6. Reconnect circuit
  7. Even if circuit is not on fire, current may still be much higher than 1 A

This is just the first thing I've found, but I suspect other behavior is wrong if this is. I suspect it is related to the noise behaviors.

@samreid - worth investigation here. if investigation is not immediately indicating what is wrong, please see if Joey/Heather need these elements for the research and if not, just hide the high voltage and high resistance things for now. I think they will be focused on regular resistors and batteries.
