Given n resistors each of resistance R, what is the ratio of the maximum to minimum resistance?
1. \(\frac{1}{n}\)
2. \(n\)
3. \(\frac{1}{n^2}\)
4. \(n^2\)

Given the resistances of 1Ω, 2Ω, 3Ω, how will we combine them to get an equivalent resistance of (11/3):

Three resistors $1 \Omega , 2 \Omega , and 3 \Omega$ are combined in series.  If the combination is connected to a battery of emf 12 V and negligible internal resistance, the potential drop across $2 \Omega$ resistor is:

1. 2 V
2. 5 V
3. 4 V
4. 6 V

Three resistors $2 \Omega , 4\Omega , and 5 \Omega$ are combined in parallel. If the combination is connected to a battery of emf 20 V and negligible internal resistance, the total current drawn from the battery is:

1. 10 A
2. 17 A
3. 13 A
4. 19 A

The current drawn from a 12 V supply with internal resistance $0.5 \Omega$ by the infinite network (shown in the figure) is:

1. 3.12 A
2. 3.72 A
3. 2.29 A
4. 2.37 A
