Question
The manufacturer of a 12 V car headlight specifies it will draw a current of 6 A. You would like to check this claim with an ammeter designed to measure currents up to 10 A and having a resistance of 0.1 Ohms. Which of the two circuits in the attached figure represents a circuit where the ammeter correctly measures the current in the headlight? You would like to check if the battery voltage drops while it is supplying a current of 6 A. You use a voltmeter designed to measure voltages up to 20 V and having a resistance of 50,000 Ohms. Which of the two circuits in the attached figure should be used? A. Circuit a. B. Circuit b.Explanation / Answer
Ammeter is connected in the series because it measures the
current which would be flowing in a single series line by a
series of electrons
Voltmeter is connected in parallel because it measures the
potential difference between two terminals(voltage) which
cannot be done when connected in series as ammeter.
so option A
option B are correct answers
