As more bulbs are added to a series circuit,each bulb will glow with __ A) the same intensity. B) varying amounts of intensity. Oc) more intensity. OD) less intensity.

D) less intensity.<br /><br />In a series circuit, all components share the same current. As more bulbs are added, the total resistance of the circuit increases. Since the voltage source is typically constant, an increase in resistance leads to a decrease in current (Ohm's Law: V=IR). With less current flowing through each bulb, they each glow less intensely.<br />
