Can a full adder circuit be used as a subtractor? If yes, draw the circuit (please ASAP TIA)

basic concepts of direct current and alternating current, and the main applications that each one has today.

Determine the CH2 peak value. Write the values only in four decimal places. the correct answer is 1.9600 please show the solution thank you!

Each terminal of a small polarity-independent incandescent bulb is connected to the positive terminals of two (2) DC voltage sources. The negative terminals of these sources are connected together. The first voltage source can have a range of value from 0-12, incrementable by 1.5 volts every turn of the rotary switch (i.e. 0 V, 1.5 V, 3 V, 4.5 V .... 12 V). The voltage of the second source is unknown. Using a luxmeter, the brightness of the lamp was measured for every increment of voltage of the first source. The following observations were recorded: a. 1.5 V produces a higher brightness than 3 V b. 0 V produces a higher brightness than 1.5 V c. 12 V produces higher brightness than 9 V d. 12 V produces equal brightness as 3 V What is the voltage of the second source? Justify each observation.

( read values &Solve Carefully and Box final answer ) Hint : Enter your answer to the 2nd nearest decimal place.

1) In a certain circuit battery is draining out 5 times more quickly than expected for normal operation what could be the possible cause for this and how did you conclude it. 2) Why AC current is preferred over DC current for high power electrical circuits. 3) Initial current across a capacitor connected across a DC source is huge and initial voltage is zero, explain why this is so. 4) Explain the working of AC generator in your own words. 5) In a Wheatstone bridge circuit a student connects a motor in place of galvanometer and is trying to find unknown resistance using formula when he adjusts variable resistor and observes that motor is no more rotating. Do you agree with his technique or not explain with reasoning. 6) What does a negative value of loop current indicates in Mesh Analysis and Method of Branch Currents, and also comment on if there a way to avoid this negative sign appearing for loop current's value.
