Important Questions on Electricity





Consider the given figure. A resistor of undefined is connected to a battery of undefined. An ammeter is connected to measure the current through the resistor and a voltmeter is connected to measure the potential difference across the same resistor. Though ideally, a voltmeter has infinite resistance and an ammeter has zero resistance, they both have finite non-zero resistances in practical situations. The voltmeter and the ammeter in the given situation have resistances of and respectively.

On the basis of the above information, answer the following question: What will be the current drawn from the battery when no voltmeter and ammeter are connected?
