I need help with this question... The manufacturer of a 12V car headlight specifies it will draw a current of 6A. You would like to check this claim with an ammeter designed to measure currents up to 10A and having a resistance of 0.1 Ohms. Which of the two figures below represents a circuit where the ammeter correctly measures the current in the headlight?

The diagram shows an voltmeter, not an ammeter ... ?

Ignoring that (assuming the voltmeter is an ammeter) what are your thoughts on the question?

just read your textbook, or use Google..

if you cant answer this by yourself you haven't made any effort.

Uhm....Voltmeters and ammeters are different things. But taking that the voltmeter is an ammeter. How do junctions affect currents and pd's ?

Maybe he meant to put a 0.1 Ohm shunt across the Voltmeter. That turns it into an ammeter.
