Q6 of 44 Page 85

Determine the equivalent resistance between points X and Y in the following circuit.

Formula used

Parallel Resistance formula



Series resistance formula




The two resistors highlighted with yellow are in series to each other & both of them are parallel to the 10 Ω resistor.


Equivalent resistance = 5Ω



These 3 resistances are in series.


Hence, total resistance is 15 Ω
