If doubling the voltage across a resistor doubles the current through the resistor, then
|
The resistor value decreased
|
|
The resistor value did not change
|
|
The resistor value increased
|
|
It is impossible to determine the change in the resistor value
|
Explanation:
Detailed explanation-1: -Hence, If doubling the voltage across a resistor doubles the current through the resistor then the resistor value did not change. It remains constant.
Detailed explanation-2: -The current will get doubled. This conforms to Ohm’s law as the current is proportional to the voltage.
Detailed explanation-3: -2. If the voltage across a resistance is doubled, what will happen to the current? Answer: The current will double as well. Explanation: If you look at the equation V= IR, if R stays the same then if you multiple V*2 (double the voltage), you must also double the current for the equation to remain true.
