1. Four identical light bulbs, each with a resistance of 20 n, are connected in series (circuit A) and placed across a potential of 12 V. a) What is the equivalent resistance of the circuit? b) What is the current in the circuit? c) If one of the bulbs burns out, the circuit is then open through that particular component, i.e., R is infinite. Would the remaining bulbs continue to burn? circuit A
