Question

2 electric bulbs have resistance in the ratio 1:3 . Connected in paralled to a source of resistance V if the 2 resistors are to be replaced by a single resistor. Calculate value of resistor

Answer 1

Answer:

The sum of the currents through each path is equal to the total current that flows from the source. You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 +... If one of the parallel paths is broken, current will continue to flow in all the other paths.
