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

The read/write heads of a hard disk gently rest on the hard disk platters in order to read and write the data.

noname [10]

The answer is FALSE because the interior of commercial Hard disk drive is with stack of magnetic disks (platters) containing the user’s data and a rotating arm supporting the magnetic heads. The rotating arm is moved by the torque generated by a voice coil motor (VCM) mounted at one end of the arm. Data read/write operations rely on the capability of the governing unit of the HDD to maintain the magnetic read/write heads as close as possible to center of the desired track. Typically, reliability of data reading and writing is guaranteed when the head is kept within 5% of the track pitch from the track center. This means that the accuracy required for the head positioning is in the range of a few tens of nanometers.
