Question

how can 3 resistors of resistance 11,9,5ohm be connected to give a total resistance of
a)25 ohm
b)4 ohm​

Answer 1

There are three resistors of resistances 2 Ω, 3 Ω, and 6 Ω respectively. Here, 6 Ω and 3 Ω resistors are connected in parallel. ... Hence, the total resistance of the circuit is 4Ω.

Answer 2

Answer:

Explanation:

A) When the three resistances are in series they add up to give 25 ohm equivalent resistance.                                                                                                        B) When 11 and 9 ohm resistors connected in series gives 20 resistor which when connected in parallel to 5 ohm resistor give a equivalent resistor of 4 ohm.
