Hey, I have a question regarding practical electricity. Since we know that power (rate of energy released) determines brightness of bulb, then: Since P = VI and V = RI, it implies 1. P =(V^2) / R 2. P = (I^2) * R How can we tell if power increases or decreases when resistance (R) of the bulb increases? Using equation 1 it seems P decreases as R increases, but using equation 2 it seems P increases as R increases. Thanks!!
