In a series circuit with three resistors connected to a power source, what would happen to the equivalent resistance and current if you removed any one of the resistors?

In a series circuit, the equivalent resistance is the sum of the resistors. Removing one resistor lowers that total resistance. With the power source voltage unchanged, Ohm’s law (I = V/R) means the current increases, so the correct choice is A: the equivalent resistance would decrease and the current would increase.
