For a metallic wire, the ratio \(V/i\) (\(V=\) the applied potential difference, \(i=\) current flowing)
1 Independent of temperature
2 Increases as the temperature rises
3 Decreases as the temperature rises
4 Increases or decreases as temperature rises, depending upon the metal
Explanation:
\(\frac{V}{i} = R\) and \(R \propto \) temperature

Ohm’s Law is true
1 For metallic conductors at low temperature
2 For metallic conductors at high temperature
3 For electrolytes when current passes through them
4 For diode when current flows
Explanation:
Ohm's Law is generally true for metallic conductors at low temperature. It states that the current through a conductor is directly proportional to the voltage across it when the temperature is constant. At high temperatures or for non - metallic materials like semiconductors (including diodes) and electrolytes, Ohm's Law may not hold as a simple linear relationship between current and voltage. These materials may exhibit non - Ohmic behavior. So option (1) is correct.

Ohm's law is applicable to
1 Diode
2 Transistor
3 Electrolyte
4 Conductor
Explanation:
Ohm's law is applicable to conductor because \(V\)-\(I\) relationship is linear for conductor.
