Application +4 | -1

We are given

n

resistors, each of resistance

r

they are first combined to get maximum possible resistance then to get minimum possible resistance then ratio between maximum and minimum resistance is

View answer and explanation

Correct option: C

n^2

Option C (

n^2

) is correct because the maximum resistance is

nr

and the minimum resistance is

r/n

, so their ratio is

n^2

The specific resistance of a wire is

\mathrm{\rho }

, its volume is

3\,\,{\mathrm{m}^3}

and its resistance is

3\,\,\mathrm{\Omega }

, then its length will be Magnitude of drift velocity per unit electric field is Statement-1: If a resistor is connected to a battery the current decreases when the temperature increases.
Statement-2: For most of the resistors, resistance increases with increase in temperature. The reciprocal of resistance is Corresponding to the resistance
