What is the effective resistance between P and Q in the given circuit |
|
Answer» Answer: All the resistance less wires that have been ATTACHED in between the three pairs of 20,30 and 40,60 resistances can be removed due to the formation of a balanced Wheatstone Bridge. So, The PROBLEM is now simple ENOUGH to CALCULATE the parallel resistance of resistances 10,50,100 and 50. So, 1/R = 1/10 + 1/50 + 1/100 + 1/50 = 10+2+2+1/100 = 15/100 So, Equivalent resistance across the points P and Q is 100/15 ohms = 20/3 = 6.67 Ohms |
