It is nearly impossible to obtain satisfactory performance from a shunt motor connected to an ac power source because the shunt winding consist of a large number of turns, due to the high number of turns that the DC shunt motor has it develops a high impedance when connected to an ac power source. and due  to this high impedance the amount of current that flows through the field will be very low making it nearly impossible for the shunt motor to operate properly

The MMC of the hole diameter is 10.10 mm. The least material condition (LMC) is the smallest size limit of a part that is acceptable for use.  LMC is the smallest allowable size limit that will still allow the part to function as intended. In this case, we will calculate the LMC for a part with a length of \(35.00 ± 0.15 mm.\)

To calculate the LMC, we must subtract the tolerance from the nominal value. The nominal value is the target value of the part dimension. In this case, the nominal value is 35.00 mm.

LMC = Nominal Value - Tolerance LMC = \(35.00 - 0.15LMC = 34.85 mm\)

Therefore, the LMC for the given part is 34.85 mm.

The Maximum Material Condition (MMC) is the largest size limit of a part that is acceptable for use. In other words, MMC is the largest allowable size limit that will still allow the part to function as intended. In this case, we will calculate the MMC of the hole diameter with dimension \(10.0 ± 0.10 mm\).

To calculate the MMC, we must add the tolerance to the nominal value. The nominal value is the target value of the part dimension. In this case, the nominal value is 10.0 mm.

MMC = Nominal Value + Tolerance MMC = \(10.0 + 0.10MMC = 10.10 mm.\)

cost of ownership for the Switch LED Lightbulb is $94.99.

To calculate the cost of ownership for the Switch LED Lightbulb, we need to first determine the total electricity cost.  We know that the bulb uses 20 watts of electricity and is estimated to last 25,000 hours. To find the total electricity cost, we need to multiply the wattage by the hours of use and the cost of electricity per kW-hr.
20 watts x 25,000 hours = 500,000 watt-hours
500,000 watt-hours ÷ 1,000 = 500 kWh
500 kWh x $0.086/kWh = $43.00
So the total electricity cost for the Switch LED Lightbulb is $43.00.
Next, we need to add the purchase price of $51.99 to the total electricity cost of $43.00:
$51.99 + $43.00 = $94.99

Explanation:

I'm thinking it is as it represents contractors who design, install, inspect and maintain amongst other activities electrical and electronic equipments or service.

In a brushless alternator, it is unnecessary to flash the field of the exciter because the excitation system does not rely on a separate DC field current to establish the initial magnetic field. Instead, brushless alternators utilize a rotating exciter, also known as a pilot exciter, which is mounted on the same shaft as the main generator rotor.

The excitation system of a brushless alternator operates based on the principle of self-excitation. When the alternator starts rotating, a small amount of AC voltage is induced in the stator windings of the exciter. This AC voltage is then rectified by diodes within the exciter to produce a DC voltage. This DC voltage is used to power the field winding of the main generator rotor, creating the magnetic field required for power generation.

Due to the self-excitation principle, once the alternator starts rotating and the initial AC voltage is generated in the stator windings of the exciter, a continuous supply of DC voltage is produced to maintain the excitation of the main generator rotor. This eliminates the need for external flashing of the field, which is typically required in older brush-type alternators that rely on a separate DC field current.

By eliminating the need for flashing the field, brushless alternators offer advantages such as simplified operation, reduced maintenance, and improved reliability. The self-excitation capability ensures that the alternator can quickly establish and maintain its magnetic field as soon as it starts rotating, making it a more efficient and convenient power generation solution.

It is worth noting that although flashing the field is unnecessary for brushless alternators, certain diagnostic or maintenance procedures may still involve the activation of excitation systems or verification of excitation performance. However, these actions are typically different from the traditional flashing process used in brush-type alternators and serve different purposes in the context of brushless alternator operation and maintenance.

The statement is false. Invoking a

subroutine

does not automatically save the contents of register r7, which typically holds the return address.

It is the responsibility of the

programmer

to ensure that the necessary registers are saved and restored appropriately when calling and returning from a subroutine.

When a subroutine is called in a computer program, the

CPU

executes a branch instruction to transfer control to the subroutine code. At this point, the return address, which is the address of the instruction following the subroutine call, is usually stored in a designated register like r7.

However, it is up to the programmer to decide how to handle the saving and restoring of registers during the subroutine execution. This includes saving the return

address

(usually stored in r7) and any other registers that need to be preserved before using them within the subroutine.

Typically, the programmer would explicitly save the contents of r7, along with any other necessary registers, at the beginning of the subroutine and restore them before returning from the subroutine. This ensures that the

original state

of the registers, including the return address, is preserved.
