How does removing a bulb or opening and closing the switch affect a parallel circuit?
How does removing a bulb or opening and closing the switch affect a parallel circuit? An obvious advantage of parallel circuits is that the burnout or removal of one bulb does not affect the other bulbs in parallel circuits. They continue to operate because there is still a separate, independent closed path from the source […]
