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
If the voltage across a fixed value of resistance is increased five times, what does the current do?
It increases by a factor of five.
It decreases by a factor of five.
It stays the same.
