Answer:
There is a short circuit in a component in the power circuit.
Explanation:
The power circuit in a computer system, regulates, rectifies and steps down power and voltage entering the main motherboard.
When a power surge capable of damaging the motherboard occurs, A component in the power circuit is shorted, not allowing the dangerous power to pass.
This can be troubleshooted by passing a high current, since the shorted component has a high emf. It over heats and is detected and changed.
Answer:
Correct answer is option (2) that is "return".
Explanation:
In any programming language, a variable name can be made up of letters (lower and upper case) and digits. we can also use "_" underscore character for declaring the variables but we cannot use any special character like “$”.We cannot use digits in the beginning of variables name. And we also cannot use reserved keywords of the language like "new","return","while" etc. There should not be space between the variable names. Options 1, 3 and 4 are not violating any of these properties. But in option (2), "return" is a reserved keyword. That is why it is not a valid variable name.
Some example of valid variables name:
foo
BAZ
Bar
_foo42
foo_bar
Some example of invalid variables name:
$foo ($ not allowed)
while ( keywords )
2foo (started with digit)
my foo (spaces )
It means the willingness to respect or except thecustoms, beliefs, or opinions of others
