Instructions

  1. Turn off the light switches and unplug appliances in the room that has lost power.
  2. Find your circuit breaker box and open the cover.
  3. Locate the tripped breaker. …
  4. Reset the breaker by moving it to the full “off” position and then back to “on.” That may clear an overload and return power to the room.

How do you test an electronic circuit?

When testing a particular transistor circuit, a multimeter can be used to determine if the voltages around the circuit are correct. To test and fault find a particular transistor circuit, it is necessary to have an idea what the steady voltages should be. The circuit below is a typical basic transistor circuit.
