Suppose that the original resistor is replaced by a resistor of the same physical dimensions but made of a material that has half the density of charges to carry current, but each carrier has double the charge of those in the original resistor. Further suppose that the potential drop across the resistor is the same as for the original The current through the new resistor will be:. a. Twice as big as for the original resistor.
b. The same as for the original resistor.
c. Half as big as for the original resistor.
d. You can’t tell from the information given.
e. Some other multiple of the original current.
