What is the difference between block box and white box testing?
White box testing or unit testing: To do white box testing, knowledge of internal logic code is required. It is mostly done by developers.Black box testing: The functionality of an application is tested; logic code is not required. This testing is done by testers.Block box or system testing: Testing the application without knowledge of underline code of the application. it is done by the testers.
Load test on single phase transformer?
The dc tests that can be done on a transformer are to measure the resistance of each windings and to measure the insulation resistance between the windings and between each winding and the transformer case.
How do you get cemilac certification?
CEMILAC certificate is given to the design of aeronautical systems and components. After thorough testing and evaluation, certificate is given
What are applications of OHM METER?
It measures resistance in a component or circuit to determine if there is a break in that circuit or component. If there's no resistance, it means there's a break, as no electrical current is passing through.
What are the type of pre commissioning testings done before commissioning a electrical substation of voltage rating 110 kilovolt?
Depending on the equipment required for the substation,some of the tests are as follows: meggering,hi-pot testing,continuity checks,c.t. testing,relay testing,ngr testing, capacitance bridge test's on transformers.
What are teased nerve fibers?
isolation of a nerve for testing
What is megging a circuit?
It`s testing the isolation of the cable. You use a isolation tester with 250,500,100Vdc depending on the cable
How to find fault in components using multimeter?
To find faults in components using a multimeter, set the multimeter to the correct testing mode for the component (such as resistance or continuity), then connect the leads to the component's terminals. Check for the expected resistance values or continuity to determine if the component is faulty. If the values are outside the expected range or there is no continuity, the component may be faulty.
Why the load must be removed when to conduct the insulation and resistance testing?
explain why all the load must be removed when to conduct the insulation and resistance testing
What skills are required for software testing?
Skills required for software testing would be communication skills with analytical and logical mindset.
What do breadboards do?
In the kin of electronics, breadboards are used for experimental testing of circuits. Once a circuit is laid out on the board, components can be easily added or taken out of the circuit. No soldering is required on the board as there are specialized clips that hold the components firmly. Once the circuit is tested and works the way it was designed to a PC board is designed to take the components
Is some animal testing required by law?
No. There is no legal requirement for animal testing.
What are the Specifications used in testing active components?
A: get that from manufacture data sheets.
What are the components in fair testing?
The components in fair testing are: A. Developing and Selecting Appropriate Tests B. Administering and Scoring Tests C. Reporting and Interpreting Test Results D. Informing Test Takers
How do you test the tcm 1994 mercury villaguer?
Testing a part like this in isolation requires specialized diagnostic equipment.
Why you use digital multimeter?
They're used for a number of purposes... testing amperage output, testing voltage output, testing circuit resistance to identify shorts or breaks in the circuit... the digital multimeters are preferred, especially in testing electronics for resistance, and they're less liable to burn out a circuit than an analog multimeter would be.
What is a phenotypic drug resistance test?
Phenotypic testing directly measures the sensitivity of a patient's HIV to particular drugs and drug combinations. To do this, it measures the concentration of a drug required to inhibit viral replication in the test tube.
