3. The drawn circuit is driven by an AC voltage function generator in 'sine wave' mode. A student has attached three identical light bulbs as drawn in the picture. Bulb #1 is in series with a resistor of similar resistance to the bulb itself. Bulb #2 is in series with an inductor. Bulb #3 is in series with a 1 capacitor. At all times the function generator is driven at a high enough 2 frequency so that flicker is not observed and so that each bulb's brightness is determined by the rms current in its particular segment a. As the student sweeps the function generator from low to high frequencies, how does the brightness of bulb #1 change, if at all? Explain. b. As the student sweeps the function generator from low to high frequencies, how does the brightness of bulb #2 change, if at all? Explain. c. As the student sweeps the function generator from low to high frequencies, how does the brightness of bulb #3 change, if at all? Explain.
