Which two points when connected to terminals X and Y would produce the highest reading on the ammeter? S & P Q & S R & Q P & Q 2 / 5 2) What is a unit of electric current? CV C S-1 VR QV 3 / 5 3) Which sentence states Ohm's Law? The electromotive force across the ends of a conductor is directly proportional to the current flowing through it. The electromotive force across the ends of a conductor is inversely proportional to the current flowing through it. The potential difference across the ends of a conductor is directly proportional to the current flowing through it. The potential difference across the ends of a conductor is inversely proportional to the current flowing through it. 4 / 5 4) What is the voltmeter reading in the circuit below, given that the ammeter reads 2.0 A? 18 V 2 V 20 V 22 V 5 / 5 5) A wire X has a resistance of 10 Ω.
