Part 1
Parts:
Breadboard
DC Power Supply
Hand Held DMM
Test leads
Wire
56kΩ resistor
1. Given the circuit below, use Ohm’s law to determine the total current in the circuit and the voltage across the resistor.
5V
My mulitsim of this circuit.
2. Construct the circuit above on the breadboard. Starting at the positive terminal of the +5 V power supply, follow the schematic around to install each component.
3. The first component is a wire that will connect the +5 V connection of the power supply to the resistor.
4. Install a 56KΩ resistor.
a. One lead will be connected in the same row as the wire that goes to the power supply positive terminal.
b. The second lead of the 56kΩ resistor can go into any other row of the protoboard.
c. Check to see that the leads are in different rows so that they are not shorted.
5. Coming from the other side of the 56kΩ resistor is a wire going to the GND connection of the power supply. Install this wire so that it is in the same row as the second lead of the resistor. Do not connect the wire to the power supply GND terminal at this time.
6. Have the professor verify the circuit.
7. Apply power to the protoboard, and measure the voltage across the +5 supply using the handheld DMM. Does the handheld DMM read +5 V (YES/NO)? If not, correct the problem and re-check the voltage. Turn off the power to the protoboard.
Yes.
8. Finish connecting the GND connection of the power supply to the protoboard. Check to see that the positive and negative terminals are connected to the correct wires. Apply power.
9. Again, measure and record the voltage at the power supply. ____4.99V______
10. Measure and record the voltage across the resistor. ____4.99V____
11. Measure and record the current between the positive terminal of the power supply and the resistor. (Note: You must break the circuit and insert the handheld DMM.) __88µA______
12. Measure and
