Q. 28 B5.0( 2 Votes )
You have four resistors of 8 Ω each. Show how would you connect these resistors to have effective resistance of 8 Ω.
Answer :
Two parallel combinations must be connected in series with each other to get the effective resistance of 8Ω. As shown in the figure below.
The effective resistance of each of the parallel combination is 4Ω. And this two 4Ω resistors are added together to get 8 Ω effective resistance.

Fearing the scolding of teacher, his group mates advised him not to tell the teacher, but he told her. On listening to him patiently, the teacher did not scold him as it was just and accident and used the opportunity to show the whole class the internal structure of ammeter.What are the values displayed by Shushant?
