A Light-Dimmer Circuit The intensity of a lightbulb with a resistance of 150 Ω is controlled by connecting it in series with an inductor whose inductance can be varied from L=0 to L=Lmax. This "light dimmer" circuit is connected to an ac generator with a frequency of 60.0 Hz and an rms voltage of 120 V. Part A: What is the average power dissipated in the lightbulb when L=0? Express your answer using two significant figures. Part B: The inductor...
Three 70.0-W, 130-V lightbulbs are connected across a ΔV = 130-V power source, as shown in the figure below. Find the total power delivered to the three bulbs and the potential difference across each. Assume the resistance of each bulb is constant (even though, in reality, the resistance increases markedly with current). An open circuit begins at a terminal with a wire extending horizontally rightwards until it reaches a lightbulb R1. After the light bulb, the wire splits downwards into...
