Why voltmeter cannot measure accurate potential difference across two points in a circuitaccording to construction it measures the potential difference in terms of current passing through it?
That is correct. At its heart, a voltmeter is just a microammeter, and it registers current, not voltage. However, that current is very, very small in comparison to the circuit being tested, so this is generally not an issue. Internally, the voltmeter places a large resistor in series with the microammeter, converting it, by Ohm's Law, into a voltmeter. You don't get something for nothing in this world. No matter how sensitive the voltmeter, in order to register an effect, you have to draw some current. The only alternative, which would not be viable outside of the lab, is to build a voltage source and make a bridge - this way you would not draw any current from the circuit under test - but that is not the way it is done in practice.
When a function is used as an argument in another function?
It is called callback function. For an example see the qsort function.
Why a function is not defined in to another function?
A function is not deigned in to another function. It is because that would lead to dependency injection.
Can you declare a function in the body of another function in c language?
yes, we can not declare a function in the body of another function. but if we declare a function in the body of another function then we can call that very function only in that particular function in which it is declared; and that declared function is not known to other functions present in your programme. So if a function is required in almost all functions of your programme so you must declare it outside the main function i.e in the beginning of your programme.
What is the difference between a function pointer and a pointer to a function?
A pointer to a function is the memory address that stores the address of a function, while the pointer itself is a function pointer.A pointer to a function might be defined as "int (*pf)(int, int);", while to actually point to the function, you would use a function pointer, such as "pf = &func;".
What is analog multimeter?
Analog multimeters use a microammeter with a moving pointer to display readings

What are the six functions of language?
The six functions of language are expressive (to express thoughts and feelings), directive (to give commands or requests), informative (to provide information), phatic (to establish social contact), aesthetic (to create beauty or evoke emotions), and metalinguistic (to discuss language itself).

What function tests a specific condition in Excel?
The IF function is the main function to do it and you can also use other logical functions, like the AND function, the OR function or the NOT function.

A function takes the exponential function's output and returns the exponential function's input?
A __________ function takes the exponential function's output and returns the exponential function's input.
Is the inverse of an exponential function the quadratic function?
No. The inverse of an exponential function is a logarithmic function.
