1. Based on Ohms Law, if a circuit component is consuming 0.12 watts of power and there is a
voltage drop of 1.2 volts across it, what is the resistance of this circuit in the correct unit?
R = 12
2. Assume that there is a re

FOR and WHILE loops
LabVIEW has only two Loop structures: FOR Loop and WHILE Loop.
FOR loop executes the code inside its border for a total of N times, where N is the value wired to
its Loop Count terminal. The Loop Count is set before the FOR Loop is ent

What is Sequence
LabVIEW is a Data Flow programming language, which means objects in a VI are not executed based on
availability of data. But in many situations it might be necessary to do things sequentially.
The way to do sequential things in LabVIEW is

LabVIEW Chart and Graph
Differences and Similarities of Charts and Graphs in LabVIEW
Charts and Graphs are objects for Plot array values
Both are front panel objects with block diagram representations as well.
Chart and Graph can display one or more plots
Label and Caption
Labels are the names of objects. Labels are a means to access/ identify/ point to objects. They are
references of objects.
Captions are additional text for describing objects, but not the names of the objects and they do not

Voltage Current Resistance
- Interconnection of electrical component
- closed circuit
has a voltage drop
- Closed circuit- electric path from and to the power source
must be a path
Charging and Discharging of Capacitor
A capacitor will charge when it is connected to a DC voltage source and it will discharge when
there is a closed circuit between its two terminals
The time it takes to charge a capacitor depends on
1. Assume a 25 volt source connected via a normally open switch to a resistor in series with a
capacitor. The value of the resistor = 10 K, and the capacitor is 0.001 uF. What is the voltage of
the capacitor after 50 mS of switch closure.

a) Describe what NYQUIST principle/theorem is.
The Nyquist principle (also called the sampling principle) states that in order to obtain adequate
data the sampling rate must be more than twice the cutoff frequency.

Concept of LabVIEW
Dataflow programming tool
Uses graphical objects, object oriented graphical programming tool
Every function is an object, and every object is premade.
Consists of interconnections between objects, functions, and entities
LabVIEW File Handling
Requirements and Types of Files
Every file must have a path and a name. A file path is a string describing the location of a file in
the file system of a computer.
The representation of a file path is platform dependent.
