Power Dissipation: Calculate Total Power

Click For Summary
SUMMARY

The discussion focuses on calculating total power dissipation in two circuits with resistive elements supplied by batteries. Participants emphasize using superposition to determine voltages and currents across each resistor. The total power dissipated can be calculated by summing the values of \(\frac{v^2}{R}\) for each resistive element in both circuits. This method ensures accurate power dissipation calculations for complex circuit configurations.

PREREQUISITES
  • Understanding of superposition theorem in circuit analysis
  • Knowledge of Ohm's Law and power formulas
  • Familiarity with resistive circuit components
  • Basic skills in circuit simulation tools (e.g., LTspice)
NEXT STEPS

I was asked to first find a few things using supersposition (A few voltages). Now it says to find the TOTAL power dissipated and there are two answers. Do I just find out all the currents(to find out all the voltages across each resitor)etc...and then sum up all the \frac{v^2}{R}'s for both of the circuits(There are two circuits..two baterries which were each shorted)?

Power will be supplied by the batteries and dissipated by the resistive elements. To find out the power dissipated by each resistive element, you can find either the current through it, or the voltage across it.
