What is a possible cause of high voltages that produce RF burns?
Pick an answer to check it.
Answer: D. The ground wire has high impedance on that frequency
If the ground wire has high impedance at the operating frequency, RF current cannot flow to ground easily and high RF voltage builds up on equipment. Touching it can cause RF burns.
Tip: High impedance ground, hot chassis.
