When you are measuring current with a clamp-on ammeter, you should ________.
A) open the jaws of the meter and place them around the wire where you want to measure the current
B) turn off all power to the circuit so that you don't get shocked
C) create an open in the circuit and place the meter probes so that the meter is in series with the load
Question 2
