The problem with electricity is that it is invisible and flows anywhere it can.
Electricity isn't really invisable... It is semi-transparent grey... When ever it can escape from those darn wires....
Cause as everyone knows electricity basically consists of magic smoke.. & as long as you kept the smoke inside the wires everything is gonna be ok...
BTW The Diode test function of a DMM typically beeps..
A DMM is a Digtal Multi Meter which is what everyone is actually talking about.. A DVM is a Digtal Volt Meter & wouldn't have an Ohm fuction...Only a Voltmeter...
