Answer:
Both Technicians are correct.
Explanation:
Remember that Ohm's Law its a relationship between Voltage (E), Current (I) and Resistance (R) in an electrical circuit. This relationship is defined by the following equation:

Each one of the letters could be called a variable. Now, also remember that the number of equations you have is equal to the number of variables unknown you could have.
In Ohm's Law you have 3 variables (E,I,R) and 1 equation. It means that you need to know 2 variables (Whatever 2 variables) to know the third.
Technician A says, in other words, that could calculate the Circuit current flow (I) knowing total circuit resistance (R) and total voltage (E). Note that Technician A knows 2 to 3 variables, then it's possible to use Ohm's Law with the following equation:

Technician B says, in other words, that could determine the unknown resistance (R) knowing total current (I) and source voltage (E). Once again, note that Technician B knows 2 to 3 variables, then it's possible to use Ohm's Law with the following equation:

It is concluded that both technicians are right.
There is no way to define the 'best' site. Each site offers a unique experience along with the fact it might not display the same information as the other ones. The APEX site (As far as I know, it is a school test site) Won't really be able to help unless you are willing to do a few tests. I would go for Scholarshipexperts.com
local stores in neighborhood do not have computerized cash registers but they may have cameras if they are in a bad neighborhood. inventory is controlled by checking the shelves.
the Qs about computers, servers and clients are for national chain stores. they use clients at each store which are connected to the central servers at HQ. employees need special training as the system is complicated. the whole system is maintained by their IT department.
