Every named object in C++ has an address. There is even a specific requirement that the size of every type be at least 1 so that T[N] and T[N+1] are different, or so that in T a, b; both variables have distinct addresses. In your case, s is a named object of type std::string, so it has an address., so it has an address.

So, when I have a schema: type Query { me: Me } type Me { hello: String } I expect a satisfying resolver to be: const resolvers = { Me: { hello() { return "Hi, me!"; } } } Alas, this isn''t the case, I have to add a dummy me-resolver (see below). Why is …
A battery produces an electric current when it is connected to a circuit. The current is produced by the movement of electrons through the battery''s electrodes and into the external circuit. The amount of current produced by a battery depends on the type of battery, its age, and its operating conditions. ...
If we consider these electrons as particles, an electric current can be thought of as the drift of these electrons in a particular direction when a potential difference is applied. Energy bands arise due to the mixing of atoms'' orbitals into molecular orbitals.
20.1: Batteries and Simple Circuits
An easy-to-understand look at how batteries and fuel cells work with photos and diagrams. It''s important to note that the electrodes in a battery are always made from two dissimilar materials (so never both from the same metal), which obviously have to be conductors of electricity. ...
At what voltage is a NiMH battery empty?

I''m using Ubuntu 14.04 and I made an empty directory on /tmp with the mkdir command: cd /tmp mkdir foo and then I checked it''s size using ls: ls -ldh foo and the result shows that the size of the directory is 4KB, although it has nothing inside! then I created an
Why do batteries only have resistance one way? They don''t. To a first approximation, a battery is a voltage source in series with a resistor. Your wrong impression is probably due to invalid measuring. You can''t just connect an ohmmeter across a …
The parallel-connected batteries are capable of delivering more current than the series-connected batteries but the current actually delivered will depend on the applied voltage and load resistance. You understand Ohm''s Law, but the "parallel batteries supply more current" statement should really be "parallel batteries CAN supply more …
This is a bit of a hack. First, let''s look at the code without that: mExitRequested.store(true); mLooperCondition.notify_all(); There''s a possible race condition here. Some other code might have noticed that mExitRequested was false and started waiting for mLooperCondition right after we called notify_all.
We know that the current (I) flows from the positive to the negative electrode in the external circuit during discharge. Does the current go from negative to positive potential inside the battery? Or is the …
Experts say "current depends on voltage". So, if the voltage is high, current would be high. Agreed; (I = V/R) If the voltage is low, the current would …
Note: If you don''t have another battery, you can jump-start the generator''s battery with a car battery. However, you should only do this if you know what you''re doing. You''ll also need at least 30 minutes for the car battery to charge the generator''s battery.
It''s hard to sure without the context, but I''d guess that the definition is given that way because all batteries have a non-zero internal resistance, $R_i$, so if a current $I$ is …
