Define a hole in a semi-conductor .
Three charges are at the corners of an isosceles triangle. The ±5.00µC charges from a dipole that is 3 cm apart.
- Find the force (magnitude and direction) the -10.00µC charge, 2 cm from the dipole, exerts on the dipole.
- For an axis perpendicular to the line connecting the ±5.00µC charges at the mid-point of this line, find the torque (magnitude and direction) exerted on the dipole by the 10.00µC charge.
Design and implement a 1-bit comparator using logic gates.
A resistor converts 415 J of electrical energy to heat in 20 minutes. Calculate the power dissipated in the resistor.
In an NPN transistor, explain why most of the emitter
injected electrons pass through the base region and on to
the collector.
How do I calculate the resistence of R2 current, which is parallel to R1 (resistence 4 ohm, current 2,25 A). Additional to that I have a resistence R3 which is a series circuit (5 ohm) next to the R1 and R2. They are all on a 24 V battery.
How many electrons pass through a conductor in 3 milliseconds if the current is 5 mA
Write a program to keep track of a match consisting of a series of games between two people: player A and player B, and report the outcome. The input consists of a sequence of letters A or B. If the input is A, it indicates that A has won a game. If it is B, then it indicates B has won a game. The first player to win 5 or more games with a difference of 2 or more games between him and his opponent wins the match. If no player wins the match in 20 games then the match is declared a tie after these 20 games have been played
Implement the following combinational logic circuits
a) Half-adder
b) Full-adder
c) Half- Subtractor
d) Full- Subtractor
What are the barrier potentials for the base-emitter (BE) and
collector-base (CB) junctions in a silicon transistor?
