Lab #02: Kirchhoff’s Laws
25 September 2019
Honor Code:
I have neither give or received nor have I tolerated any other’s use of unauthorized aid
OBJACTIVE:
The objectives of this experiment are to:
· Verifying Kirchhoff’s Current Law (KCL)
· Verifying Kirchhoff’s Voltage Law (KVL)
COMPONENTS:
· Voltage Sources
· LED
· Connecting Wires
· 6 Resistors (82 ohms)
THE TESTED CIRCUIT:
Figure 1. Test Circit
PROCEDER:
1_ At the circuit given in Figure 1 is fixed on a bread board utilizing resistors, LED and connect Wires. And one power supply is connected in the left side, and other at the right side. Power supplies were not turned on so far.
2_in this experiment, the power supply voltage is set to be 6V (±0.02) V. And The LED is connected in the circuit with right extremity generally so it can turn on. The long wire of the LED is connected with positive or higher side of the voltage supply and the short wire is connected with the ground or lower voltage side.
3_Voltages crosswise over resistors VAB, VBC, VDC and VDE are then estimated by me. These voltages are the voltages between particular nodes demonstrated by the subscripts.

Table 5. Currents flowing throgh resistors (mA)
ANALYSIS:
In Figure 1, there are four meshes. Along these lines, we have to apply the following equation all the four meshes. While circling through the cross sections, a few voltages will be positive, and couple will be negative.
As we know, Kirchhoff’s Current law states that sum of the currents distributing in a node is zero.

Table 6. Voltage calclations of each mesh.
The Values found in Table 6 are non-zero, despite the fact that these Values should respect zero as indicated by Kirchhoff's voltage law.
Kirchhoff's Current and Voltage laws establish the framework of electric circuits. These laws have been checked tentatively, despite the fact that there is some distinction in the hypothetical and trial Values because of individual and methodical blunders. Such blunders can be limited by taking suitable measures.
