Question

Solve all these correctly. Part A refers to Resistors in series, Part B refers to Resistors in parallel and Part C refers to Resistors in series-parallel. Note: there is no image for any part. Thanks

2. diagrams resistances of light bulbs in such circuits When a Suppose that the resistors in the various circuit represent the R the remaining bulbs light bulb "burns out the circuit is open through that particular component is infinite. Would continue to burn for the following conditions? If so, would the bulbs burn more brightly (draw more current) or burn more dimly (draw less current), if (a) R2 burned out in the circuit in part A? (continued)

Explanation / Answer

Part A

bulbs are in series

if one of the bulb fails circuit becomes open so no current flows

So other bulbs will not burn

Part B

in parallel connection

if a bulb fails it will not effect other bulbs

other bulbs burn at the same rate

Part C

if bulbs are in parallel and series

if a bulb fails then all the bulbs whcih are connected in series with the damaged bulb will not burn
