Answer:

<u>GFCI</u> - <em>" Ground Fault Circuit Interrupter" </em>

Working Principle - The GFCI operates by measuring the flow of current into the circuit to that of flowing out. And then operate as accordingly to the situations.

Importance - The GFCI are used for the purpose of protection against electrocution and mainly are installed where the circuit may come in contact with water.

Explanation:

If the difference between the current leaving and returning through the current transformer of the GFCI exceeds 5mA, the solid-state circuitry opens the switching contacts and de-energizes the circuit.

As the GFCI can detect the current even in amount of currents as small as 4 to 5 milliamps. Now in case there is any leakage current from the circuit, so , the GFCI will respond by shutting off the system or circuit in order to avoid any sort of loss.

Answer:

The GFCI shuts down the circuit when it senses a current leakage.

Explanation:

The ground of a circuit should truly be ground. But if the ground circuit is not truly ground, then someone could get shocked. The GFCI monitors the possibility of current flow to ground. If this occurs, then the GFCI stops all flow of current, for safety reasons.

It also monitors if the current flow is interrupted. Say you drop something that is plugged in, into a sink of water. The GFCI should note the current loss, and shut down the circuit.

GFCI stands for: Ground-Fault Circuit Interrupter

Does a triangle with sides of lengths 1.5 ft, 2.5 ft, and 2 ft form a right triangle? How do you know?

timama [110]

Answer:

Yes, the side lengths of 1.5, 2.5, and 2 ft form a right triangle.

Explanation:

Before we solve this problem, we need to know a couple of things.

In a right triangle, you have two legs and a diagonal line that goes from one leg to the other or from one side to the other. This line is called the hypotenuse. It is the longest side of a right triangle. This length can be calculated by using a special formula that is over a thousand years old.

The formula is called the Pythagorean Theorem.

The formula states that if you square one leg and the other leg and add it up. You get the side of hypotenuse which is squared as well.

Here it is in simple terms: $a^{2} +b^{2} =c^{2}$ .

a and b are your two legs.

C is your hypotenuse.

In this case 1.5 and 2 are your legs and 2.5 is your hypotenuse since it is the longest side.

Before we calculate, there is a converse to the Pythagorean Theorem.

If $a^{2} +b^{2} \neq c^{2}$ , then it is not a right triangle.

Lets make 1.5 for a

and 2 for b.

We know 2.5 is for c.

Here it is.

$1.5^{2} +2^{2} =2.5^{2}$ . The / means it is a fraction.

1.5 squared is 9/4 and 2 squared is 4. Add 4 and 9/4 and you get 25/4 squared. Take the square root of 25/4 and you get 5/2.

5/2 is equal to 2.5, so the Pythagorean Theorem applies to this triangle. Therefore, these side lengths do form a right triangle.

Hope this helps!

Allocate 100 integers and assign the resulting pointers to the elements of ip_arr. Initialize each integer value to -1.

dmitriy555 [2]

Answer:

#include <iostream>

using namespace std;

int main() {

int *ip_arr,n;//pointer name inp_arr and integer n to store the size.

cin>>n;//size.

for(int i=0;i<n;i++)

ip_arr[i]=-1;//assigning -1 to every element.

for(int i=0;i<n;i++)

{

cout<<ip_arr[i]<<" ";//printing every element.

}

return 0;

}

output:-

100

-1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1

Explanation:

I am taking input of size.You should enter 100 for 100 values which have value -1.
