Answer 2

Given :

Three resistance each of 5Ω are connected in a circuit.

To find :

Maximum equivalent resistance due to their combination obtained

Solution :

We can obtain maximum resistance, when resistors are connected in series combination.

$\bigstar$ The combined resistance of any number of resistances connected in series is equal to the sum of the individual resistances. .i.e.,

➠ R = R₁ + R₂ + R₃

➠ R = 5 + 5 + 5

➠ R = 15Ω

thus, maximum equivalent resistance due to their combination obtained is 15Ω

Hence, option (c) 15 ohms is correct.

Remember !

SI unit of resistance is ohms (Ω).
