If you have a constant current source passing through a resistor, then, yes, increasing the value of the resistor will increase the voltage drop across it. Ohm's Law gives the resistance as the ratio of the voltage and current, as R = V/I.

What do resistors do to voltage?

Resistors ensure components receive the proper voltage by creating a voltage drop, and they can protect a component from voltage spikes. ... If a component in your circuit requires less voltage than the rest of your circuit, a resistor will create a voltage drop to ensure the component does not receive too much voltage.

Can a resistor increase current?

In a series circuit, adding more resistors increases total resistance and thus lowers current. But the opposite is true in a parallel circuit because adding more resistors in parallel creates more choices and lowers total resistance. If the same battery is connected to the resistors, current will increase.
