Given \(n\) resistors each of resistance \(R,\) what is the ratio of the maximum to minimum resistance?
1. \(\dfrac{1}{n}\)

2. \(n\)

3. \(\dfrac{1}{n^2}\)

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 $\mathrm{}$\(2~\Omega, 4~\Omega\)and\(5~\Omega, \) are combined in parallel. If the combination is connected to a battery of emf \(20~\text V\) and negligible internal resistance, the total current drawn from the battery is:
1. \(10~\text A\)
2. \(17~\text A\)
3. \(13~\text A\)
4. \(19~\text A\)

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

    
1. \(3.12~\text{A}\)
2. \(3.72~\text{A}\)
3. \(2.29~\text{A}\)
4. \(2.37~\text{A}\)
