Objectives: To calculate the power in the voltage and the power in each resistance and compare the calculated values in ltspice

Objectives:

1. 
   To calculate the power in the voltage and the power in each resistance and compare the calculated values in LTspice.
   
2. 
   To check if the power delivered is equal to the power absorbed in the circuit.
   

Table 1

Element	Pv1	Pr1	Pr2
Expected values	110W	10W	100W
Measured values	110W	10W	100W
%error	0%	0%	0%

In table 1, the results of the computed values are equal to the measured values and the power delivered is equal to the power absorbed in the series circuit.

Table 2

Element	Pv1	Pr1	Pr2	Pr3
Expected values	110.908W	10.163W	9.98W	90.763W
Measured values	110.91W	10.165W	9.98W	90.759W
%error	0.0018%	0.02%	0%	0.004%

In table 2, some results have a slight error but if you round off the values, they are still equal and the power delivered is equal to the power absorbed in the parallel circuit.

Conclusion:

Some of the results of the computed and recorded power are accurate and some have a very slight error but still the same if you round them off so, all the computed and recorded values are accurate. Based on the results, we can say that the total power is equal to the sum of the power of each component on both series and parallel circuit.
