A multirange voltmeter which scale is numbered from 0 through to 250 the pointer falls mid range on the scale interpret the reading on the meter?

With the pointer mid range on the scale, the reading of the multi-range voltmeter would be 125 volts.

In C programming what is pointer?
Simply put, a pointer is a memory address. It "points" to data at that address. The Data Type of the pointer tells the program how to interpret the data at the address. For example, a character pointer will read the data at the address as a byte and interpret it as a character (like an ASCII character, for instance). A string pointer is just like a character pointer, except that it starts reading characters at the address and keeps going until it encounters a null (a data value of zero). The "string" of characters is interpreted as text. The available data types include just about anything you can imagine. Intrinsic types, structures, functions... in later versions of C, pointers can point to objects.
What is the actual error percentage in calibration of voltmeter?
An ordinary voltmeter would be expected to have an accuracy of about 1%.Even then, if it were an analog meter, one should check the balance of the pointer; along its pointer axis, and perpendicular to that. Indeed, this is the reason that an analog meter should be used with the scale plate horizontal if possible.To check the balance of the needle assembly, hold the meter up so that its scale plate is vertical. Then check the balance of the pointer as above, in both vertical and horizontal attitudes.To do better than this, with either an analog or a digital instrument, you will need access to a set of standardized voltages, and some more elaborate equipment.
What does voltmeter measures?
voltage in a circuit (also known as potential difference p.d.)A voltmeter or multimeter is an electrical instrument capable of measuring voltage, current, and resistance. Digital multimeters have numerical displays, like digital clocks, for indicating the quantity of voltage, current, or resistance. Analog multimeters indicate these quantities by means of a moving pointer over a printed scale.
Difference between pointer to constant and constant pointer?
1. pointer to a constant means you can not change what the pointer points to 2. constant pointer means you can not change the pointer.
What is triple pointer?
Example: int x; -- integer int *px= &x; -- pointer to integer int **ppx= &px; -- pointer to pointer to integer int ***pppx= &ppx; -- pointer to pointer to pointer to integer
What are pointer to pointer?
A pointer only holds an address information (location) in the memory. if a pointer holds points another pointer then it is a pointer to an other pointer. Pointer holds an address in the memory so in that address there is an other location information that shows another location.
What is pointer of pointer?
pointer is the variable that holds the address of another variable
Why is double pointer used?
Double pointer is a pointer to a pointer. So you can work with the double pointer as you work with a single one.Or you might mean 'pointer to double', eg:void clear_double (double *dp){*dp = 0;}
Define pointer to pointer in c?
Double (**) is used to denote the double pointer. As we know the pointer stores the address of variable, Double pointer stores the address of any pointer variable. Declaration : int **ptr2Ptr;
C program pointers to pointers examples?
Pointer to Pointer is a double pointer, denoted by (**). Pointer stores the address of the variable and pointer to pointer stores the address of a pointer variable and syntax can be given as int **ptr2ptr;
What is void pointer and what are its uses?
Void pointer can hold the address of any kind of pointer. But we can't operate on void pointer
What is the mouse pointer?
