Question

Which has more resistance, carbon or copper? With the same voltage applied, which resistance will allow more current, 4.7 Ω or 5k Ω.

Answer 1

Answer:

copper is high resistance than carbon beacuase copper having electrical properties

Answer 2

Concept introduction:

According to Ohm's law, under normal circumstances and at constant temperatures, the voltage across a conductor is precisely proportional to the current that passes through it.

Explanation:

Given that, resistance $4.7$ Ω or $5$k Ω

We have to find, which resistance will allow more current and among carbon and copper which will allow more current to flow.

According to the question,

Carbon is non metal whereas copper is good conductor hence carbon has more resistance than copper.

According to Ohm's law current and resistance is inversely proportional hence more resistance lesser the current hence resistance of $5$kΩ will allow lesser current to flow.

Final Answer:

Carbon has more resistance than copper. $4.7$Ω resistance will allow more current to flow.
