In a circuit, the resistor serves to oppose an electric current. How does a resistor affect the electrical current flowing through a given circuit that is supplied with a constant voltage?


I can't seem to figure this out! Can someone help please? Thank you!

I wouldn't say a resistor "opposes" current but rather it RESTRICTS the amount of current in a circuit where the voltage of the source remains constant.   That's assuming this question refers to a simple circuit of only the power supply and a resistor.  If not, then the circuit must be defined in order to answer correctly.
