प्रश्न
What is the resistance of a conductor through which a current of 0.5 A flows when a potential difference of 2V is applied across its ends?
उत्तर
Given, I = 0.5 A
Potential difference, V = 2 V
Applying ohm's law, V = IR
Or, R = `"V"/"I" = 2/0.5 = 4 Omega`
Hence, the resistance of a conductor is 4 Ω.
