Question

Question 8 0/ 1 point For measuring voltage and current, a voltmeter and ammeter are used. How should these measurement devices be hooked up to measure the voltage drop across a resistor and the current running through it? The voltmeter and the ammeter should be in series with the resistor The voltmeter and ammeter should be parallel to the resistor The voltmeter should be parallel to the resistor and the ammeter should be in series with it The voltmeter should be in series with the resistor and the ammeter should be parallel to it

Explanation / Answer

the Voltmeter measures the voltage across two points,and it should not loss the current,so it is connected in parallel combination ,and ideal voltmeter should has infinite resistance

coming to ammeter it measures the current in the circuit,so all the current should be passed through that which is going to be measured .Hence the ammeter should be connected in series

so the answer is The Voltmeter should be parallel to the resistor and the ammeter should be in series with it
