Question

Part 2

Parts:

Breadboard

DC Power Supply

Hand-Held DMM

Test leads

1k? resistor

3.3k? resistor

1. Using Ohm’s Law, calculate the total current in the circuit above. Then, determine the voltage drop across R1. Record the results in Table

2. Connect the breadboard to the +5 V supply by connecting the ground (-/Blue) and positive stripe (+/Red) of the breadboard to ground and +5 V connections on the DC power supply.

3. Verify the +5 V voltage by using the hand-held DMM.

a. Connect the hand-held DMM leads as shown below. Have the professor verify the connections.

   b. Set the hand-held DMM to measure voltage. Choose the appropriate scale.

c .Turn on DC power supply.

d. What voltage did the hand-held DMM read? __________. Is this correct (YES/NO)? If not, correct the problem and make the measurement again.

Explanation / Answer

1. Current

V=IR

5 V = I x 1k Ohm

I => 0.005 Amp (5 mili Amp)

if R = 3.3K Ohm

I => 0.0015 Amp ( 1.51 mili Amp)

3.d

Hand Held DMM reads +5 V. (DC) Yes its correct.
