Question

Two resistors, 400 $\Omega$ and 800 $\Omega$ are connected in series with a 6 V battery. It is desired to measure the current in the circuit. An ammeter of 10 $\Omega$ resistance is used for this purpose. What will be the reading in the ammeter? Similarly, if a voltmeter of 1000 $\Omega$ resistance is used to measure the potential difference across the 400 $\Omega$ resistor, what will be the reading in the voltmeter?

Answer 1

reading of ammeter is 4.9mA

n reading of voltmeter is 30/19V=1.579V
