Question

1. (TCO 1) Which variable is measured along the horizontal axis of an oscilloscope?
voltage
current
resistance
time

2. (TCO 2) If the current through a 9V flashlight bulb is 20mA, what is the resistance of the bulb?
180?
222?
450?
1.8k?

3. (TCO 3) A series circuit consists of a 100?, a 330?, and a 510? resistor. Which resistor has the largest current flow?
100?
330?
510?
equal for all

4. (TCO 4) A circuit consists of 6 resistors of different values in parallel. Each resistor has: (Points : 5)
the same current
the same voltage drop
the same power dissipation
all of the above

5. (TCO 5) What is the result of the binary subtraction 0110

Explanation / Answer

1 Time variable is measured along the horizontal axis of an oscilloscope.
2 450 is the resistance of the bulb
3 A series circuit consists of a 100, a 330, and a 510 resistor.
     resistor has the equal for all current flow

4 A circuit consists of 6 resistors of different values in ||. Each resistor has: (Points : 5)

    the same current ,the same voltage drop ,the same power dissipation.

5 The result of the binary subtraction 0110 – 0011 = 011

6 A EX-OR B = A.B BAR + ABAR .B

    Boolean expressions represents an exclusive-OR gate
