When an inductor and a resistor are connected in series with a constant voltage source, what is the behavior of the current through the circuit over time?
a. The current increases exponentially and eventually reaches a steady-state value determined by the resistor.
b. The current decreases exponentially and eventually approaches zero.
c. The current oscillates continuously due to the combination of inductive and resistive effects.
d. The current remains constant throughout the circuit, equal to the voltage divided by the resistance.
