Question

Two dissimilar bulbs are connected in series, which bulb will be brighter ?

• A. low resistance bulb
• B. more resistance bulb
• C. high current pass bulb.
• D. low current pass bulb

Answer 1

The correct option is B more resistance bulb

Components connected in series are connected along a single path, so the same current flows through all of the components. The current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component.
When two bulbs are connected in series the first bulb will receive more current. As the bulb has its own resistance, less current will flow to the next bulb.
Hence the first bulb will glow more.
