Agalvanometer has a coil with a resistance of 24.0 ω, and a current of 180 μa causes it to deflect full scale. if this galvanometer is to be used to construct an ammeter that can read up to 10.0 a, what shunt resistor is required?

as technology advances, new experiments often expose problems in accepted theories. c

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
