Answer #1

Testing of a Vacuum cleaner using Digital Multi Meter:-

-->Set the multimeter knob to the resistance measurement position.

-->Connect the probes to the terminals of the vacuum cleaner.

-->Here is the connection diagram

-->For a good working machine the resistance shown in the DMM will be a small value and it should not be equal to zero.

-->Observe the reading if the reading shows 0 resistance, it means the motor winding present in the vacuum cleaner is short-circuited.

-->If the reading shows very high value or it displays value beyond its range, then the winding of the motor is damged and is open circuited.

2. You are using a digital multimeter (DMM) to measure the voltage across a resistor. The values displayed on the DMM vary, with five consecutive values being 2.412, 2.432, 2.418, 2.422, and 2.416 V (this happens even though no connections are changing). These fluctuations give rise to an uncertainty in the measured value of resistance. a) (1 point) One method of quantifying the uncertainty in the measurement is to take half of the range of the largest fluctuating digit. Using...

Please answer quickly! Thank you. Java: Write a non-static method to be added to a class that implements a singly linked list of integers. The method is called make_partition() and takes an integer x as input. The method should modify this list by moving all the elements less than x to the front of the list, and all the elements greater than x to the back of the list. It is not the important for the elements to be kept...
