Resistance and Volts are:

Resistance and Volts are:

• A. Directly proportional
• B. Inversely proportional
• C. Independently related
• D. Logarithmically related

Answer: (A)

Ohm’s law ties voltage, current, and resistance together: V = I × R. If the current through the circuit is kept constant, voltage changes in direct proportion to resistance. Doubling the resistance doubles the voltage, so voltage and resistance rise together in a straight-line relationship—this is direct proportionality. If current isn’t fixed, the relationship isn’t simply proportional, since V depends on both I and R. However, in the typical view of how resistance relates to volts in a straightforward sense, holding current constant makes the direct proportionality the correct interpretation.
