In series RL circuit, some energy is dissipated by the resistor and some energy is alternately stored and returned by the inductor-The instantaneous power deliver by voltage source V is P = VI (watts). However, you DO have the current in the branch and that does flow through the 6 Ohms, so you can use the I 2 R formula for the resistance. Voltage hysteresis happens when a system's electromagnetic response to input is delayed so the system state changes between the input receipt and the response. However, if you increase the value of the resistor, current will decrease, and the resistor’s power dissipation will decrease as well. The PE is defined as*: work = charge x potential difference .
