Observe the given figure. If the diode is an ideal diode, then what are the values of Io and Vo respectively?

Io = V/R = 20/100

Io = 0.2 A

Since the given diode is an ideal diode therefore there is no voltage drop across it.

Vo = Io × RD

Vo = 0.2 × 0

Vo = 0

Hence Io = 0.2 A & Vo = 0

_____type of single phase induction motor operates at better power factor at full load?

This type of motor is designed to operate with the start winding and it’s series capacitor permanently connected to the supply. lt has two capacitors connected in parallel in the start winding circuit for starting purposes. The running capacitor is employed to correct the power factor. As a result, this motor has a higher starting torque as well as a higher efficiency. These motors are employed in sizes ranging from 375 W to 7.5 kW. The power factor of these motor is upto 80% to 100%.

When capacitors are connected in series across DC voltage then_____

When voltage is applied across the capacitor one plate becomes negatively charged with electrons leaving the battery. At the same time, electrons leave the other plate to resupply the battery, leaving that plate positively charged. This effect is called polarisation. The current flows until the charge across the capacitor is equal to the battery emf, at which point everything stops.

In series connections, the same charging current flows through all capacitors as soon as a voltage is applied. Hence in a series connection same current flows through each capacitor.

The 2’s complement of 1010101 is

The 2’s complement of the number (1010101)2 is found in two steps. First, convert the given number into its l’s complement.

1’s complement of a binary number is just an inversion of individual bits.

1’s complement of (1010101)2 is (0101010)2

To find 2’s complement of the number add one to the least significant bit (LSB). So
