WebThe bulb in a circuit glows only when the circuit is closed and the current is flowing. Suggest Corrections 1 Similar questions Q. If an electric switch is open then no current flows through the circuit. Q. Electric current only flows when a circuit is closed. Q. You want to make an electric circuit in which electric current makes a bulb glow. WebHence most of the supplied voltage (the electrical energy) reaches the bulb. Hence it glows brighter. Now in the case of series combination of resistors, the effective resistance of the circuit increases. This in turn maximizes the voltage drop across the effective resistance as the voltage drop across each resistancee adds up.
