The disk address specifies the location of the data on the disk in terms of cylinder, head, and sector. This information allows the disk drive to locate where the specific record is stored on the physical medium of the disk.

To find the input current in the chopper circuit, we can use the formula for power, which is:[ text{Power} = text{Voltage} times text{Current} ]The output power ((P_{out})) is given as 16 watts, and the efficiency ((eta)) of the chopper is 80% (or 0.8).

To find the input current in the chopper circuit, we can use the formula for power, which is:
[ text{Power} = text{Voltage} times text{Current} ]
The output power ((P_{out})) is given as 16 watts, and the efficiency ((eta)) of the chopper is 80% (or 0.8). The input power ((P_{in})) can be calculated using the efficiency:
[
eta = frac{P_{out}}{P_{in}}
]
So, rearranging this gives us:
[
P_{in} = frac{P_{out}}{eta} = frac{16 text{ watts}}{0.8} = 20 text{ watts}
]
Now, we know that the input power is also equal to the product of the input voltage and the input current:
[
P_{in} = V_{in} times I_{in}
]
Plugging in the values:
[
20 text{ watts} = 20 text{ V} times I_{in}
]
Now, solving for (I_{in}):
[
I_{in} = frac{20 text{ watts}}{20 text{ V}} = 1 text{ A}
]
Thus, the value of the input current is 1 A.
