This is my circuit. I need to find the power dissipated by
Vlamp. So the lamp turns on if the
Vlamp is more than 2V. When the lamp is on it has an internal resistance of 10 Ohms, and when it is off it acts like an open circuit.
How would I find the power dissipated? I know how to do it for Voltage sources and Resistors, but not elements like these.
One more thing, I already figured out that:
Battery has open circuit voltage of 4V
R1 = 5 Ohms
R2 = 5 Ohms
k = 0.2A/V
When lamp on and Vlamp = 2V, Rbat = 10 Ohms
