10 resistors, each of resistance are connected in series to a battery of emf and negligible internal resistance. Then those are connected in parallel to the same battery, the current is increased times. The value of is:
To solve this problem, we need to analyze the two different configurations of the resistors: series and parallel.1. Series Configuration:• When 10 resistors, each of resistance are connected in series, the total resistance is given by:• The current through the series circuit is given by Ohm's Law:2. Parallel Configuration:• When the same 10 resistors are connected in parallel, the total resistance is given by:10 times• The current through the parallel circuit is given by Ohm's Law:3. Comparing the Currents:• The problem states that the current increases times when the resistors are connected in parallel.• Therefore, we have:Substitute the expressions for and Simplify the equation:Therefore, the value of is This corresponds to Option 2.
