Transcription: In this lesson we will discuss power relationships in parallel circuits. All the resistors in the circuit diagram shown dissipate power in the form of heat. The power dissipated in each resistor is determined by the following equations. For R1, P1 is equal to E squared divided by R1 or E times I1 which is equal to I1 squared times R1. For R2, R2, the power is P2 which is equal to E squared divided by R2 which is equal to E times I2 which is equal to I2 squared times R2. And for R3, the power is equal to E squared divided by R3 which is equal to E times I3 which is equal to I3 squared times R3. ...
