gimme some question related to equivalent resistance....but question should be at iit level.
plz give atleast 5 questions of iit
Answers
1.. How much resistance must be applied between points A and B for the circuit to have a total current of 3A
2.. What is the current through the system if we attached a resistor from a point..
3. If the equivalent resistance of a current to circuit and each resistor is same what is the value of each resistor..
Answer
I'm having hard times understanding why when you combine 20 and 30 resistances which are in parallel, and then combine 60 and 40 (which are also in parallel) ohms resistances you will get two parallel resistances? Aren't they supposed to be in series when you combine 20 and 30, 60 and 40?
And if the question was asking the equivalent resistance between terminal b and a but not a and b, would it be just the equivalent resistance of 60 and 40 ohms resistances?
Also, if there was no wire in the middle, would 20 ohms resistance be in series with 60 ohms resistance as well as 30 ohms be in series with 40 ohms resistances?
