Why is it dangerous to leave a test lead in the high-current jack and then measure a voltage?

Select one answer.

• The current jack is nearly a short (very low resistance), so touching it across a voltage places a near-short through the meter — blowing the fuse or creating a hazard.
• Nothing happens; the jacks are electrically identical.
• The current jack has very high resistance, so it safely reads any voltage.
• It makes the reading more accurate, so it's the preferred method.
