LAB REPORT 5 To construct resistive circuit based on Kirchhoff’s Voltage Law (KVL) and measure the circuit parameters using hardware and software tools. Objective: • •

To construct series and parallel resistive circuits based on KVL and measure the circuit parameters using hardware tools. to construct series and parallel resistive circuits based on KVL and measure circuit parameters using software tools.

Required Equipment: Hardware: • • •

BREADBOARD DMM RESISTORS

Software: •

LTSPICE

Methodology: In first step, I took three resistors and made different circuit like series and parallel. In the next step, I located the nodes for voltages to measure at certain points. If I talk about one of the given circuits, the points will be written as 1-2,1-3,1-4,2-3,2-4,3-4. Thus, the measured voltages would be followed as V12, V13, V14, V23, V24, V34. These small subscript numbers tell us the +ve and -ve terminals i.e.in V12, 1 is for +ve terminal and 2 is for -ve terminal. I measured all the voltages according to the points and noted them all and verified equations for KVL.

LAB TASK 1:

Measured Voltages: V12 = 73V

V13 =92V

V14 = 100V

V23 = 19V

V21 = – 73V

V31 = – 92V

V41 = – 100V V32 = – 19V

V24 = 27V

V34 = 8V

V42 = – 27V

V43 = – 8V

Verification Voltages: V41 + V12 + V23 + V34 = – 100 + 73 + 19 + 8 = 0 V41 + V12 + V24 = – 100 + 73 + 27 = 0 V41 + V13 + V34 = – 100 + 92 + 8 = 0 V41 + V14 = – 100 + 100 = 0 V42 + V23 + V34 =– 27 + 19 + 8 = 0 V42 + V24 = – 27 + 27 = 0 V43 + V34 = – 8 + 8 = 0

V14 + V43 + V32 + V21 = 100 – 8 – 19 – 73 = 0 V14 + V43 + V31 = 100 – 8 – 92 = 0 V14 + V42 + V21 = 100 – 27 – 73 = 0

V14 + V41 = 100 – 100 = 0 V13 + V32 + V21 =92 – 19 – 73 = 0 V13 + V31 = 92 – 92 = 0 V12 + V21 = 73 – 73 = 0

LAB TASK 2:

Loop 1 (4-1-2-4) V41 = – 99.756

V12 = 99.958

V24 = 0.202

V41 + V12 + V24 = – 99.756 + 99.958 + 0.202 = 0.202 LOOP 2 (4-2-3-4) V42 =– 0.202

V23 =0

V34 =0.202

V42 + V23 + V34 = –0.202 + 0 + 0.202 = 0 LOOP 3 (4-1-2-3-4) V41 = –99.756

V12 = 99.958

V21 = 0

V41 + V12 + V23 + V34 = –99.756 + 99.756 + 0 + 0.202 = 0.202

LAB TASK 3:

LOOP 1 (1-3-2-1) V13= 0 V21 = 37.02 V32 =V13 + V21 = 0 + 37.02 = 37.02 Measured V32 = 37.02 LOOP 2 (2-3-4-2) V34 =58.676 V42 =21.656 V23 = – V34 – V42 = – 58.676 – 21.676 = –37.05 Measured V23 = –37.05

Conclusion: I have learnt how to construct series and parallel resistive circuits based on KVL and measure circuit properties using hardware and software tools. THE END ………
