What is the basic difference among Circuit
breaker,Contractor and Isolator?
Are they different names of same device/equipment?
Answer Posted / iamdon
circuit breaker can make,break and carry current under
normal,short circuit and overloaded condition..It operates
automatically.
contactor can make,break and carry current under normal and
overloded conditions only but not in short circuit
condition.It can operates more no of times without
maintenance.
Isolator can break currnt only through that part of circuit
which is bot carrying any current.It is manually operated..

54 Comments Alok and Bhanu play the following min-max game. Given the expression N = 38 + X*(Y – Z) where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be?
