    The responsibility of the logical unit in the CPU of a computer is to perform all logical operations and comparisons. This includes executing operations such as AND, OR, NOT, and XOR, as well as comparing numbers to determine equality or order. The logical unit works in conjunction with the arithmetic unit to process data and make decisions based on logical conditions, enabling the CPU to execute complex instructions and algorithms.

    Added an answer on August 18, 2024 at 9:29 am

    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.

    A chopper circuit is fed from an input voltage of 20 V delivers a power of 16 watts. If the chopper efficiency is 80 %, then find the value of input current.

    Added an answer on August 18, 2024 at 1:23 am

    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 uRead more

    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.
