Question

Question 1 (1 point) Resistance of a wire depends upon voltage of the battery it is connected to. True False Question 2 (1 point) Consider a light bulb with Resistor R is connected to voltage source V and the current is 1_1. If the voltage difference is doubled and resistance is kept same the new current is I_2. Can we say 11-2*1 2? True False
