The equivalent resistance between A and B is:
0.5
1
2
4
Two parallel combination of resistors:
Rparallel = 1×11+1 = 12 for both of them.
Now, they are in series:
R = 0.5 + 0.5 =1
The equivalent resistance between A and B in the circuit shown in figure is
The value of b if f(x)=x2+4√x+b and f(16)=275 is:
