Electric current flows through three lamps when arranged in $(a)$ a series $(b)$ a parallel. If the filament of one lamp breaks. Explain what happens to the other two lamps in both the cases.
Electric current flows through three lamps when arranged in $(a)$ a series $(b)$ a parallel. If the filament of one lamp breaks. Explain what happens to the other two lamps in both the cases.
$(a)$ In a series combination if one lamp breaks other lamps stop to glow.
$(b)$ In a parallel combination if one lamp breaks other lamps glow normally.
