When 1 ampere of current flows through a resistance by the application of 1 volt, what will the resistance be?

The scenario describes a relationship defined by Ohm's Law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor. Mathematically, this is expressed as:

[ V = I \times R ]

where ( V ) is the voltage in volts, ( I ) is the current in amperes, and ( R ) is the resistance in ohms.

In this case, when 1 ampere of current flows through a resistance due to the application of 1 volt, we can rearrange Ohm's Law to solve for resistance:

[ R = \frac{V}{I} ]

Substituting the given values:

[ R = \frac{1 \text{ volt}}{1 \text{ ampere}} = 1 \text{ ohm} ]

Thus, the resistance is 1 ohm, confirming that "Ohm" is the correct answer.

The other options, such as watt, joule, and ampere, refer to different electrical concepts. Watt is a unit of power, joule is a unit of energy, and ampere is a unit of electric
