One ohm is equivalent to:

Correct option is C

Correct Answer: (c)
Explanation
According to Ohm's Law:
R = V / I
Where:
· R = Resistance (Ohm, Ω}
· V = Potential Difference (Volt}
· I = Current (Ampere}
Therefore,
1 Ω = 1 Volt / 1 Ampere
Hence, the correct answer is Option (c}.
Additional Information
Important SI unit relations:
• 1 Volt = 1 Joule / 1 Coulomb
• 1 Ampere = 1 Coulomb / second
• 1 Watt = 1 Joule / second
• Combining these,
1 Ω = 1 V / 1 A
This is the SI definition of electrical resistance.
