Electrostatics and Magnetostatics — UPSC Physics Optional IFoS 2018 Paper I

Two resistors of 600~\Omega and 800~\Omega are connected in series with a 7\text{ volts} battery. An ammeter of 10~\Omega resistance is used to measure current.

(i) What will be the reading in the ammeter?

(ii) Similarly if a voltmeter of 10000~\Omega resistance is used to measure the potential difference across the 600~\Omega resistor, what will be the reading in the voltmeter?
