Identical light bulbs are connected to an EMF as shown. Assume the light bulbsare chmic and the EMF is ideal. What happens to the brightness of the bulbswhen a short, 5 (dashed red line), is connected across the points shown?Remember brightness is proportional to power.Before switch S is in place, the brightness of bulb 1 is B₁. What is the brightnessB₁' of bulb 1 when the switch, S, is in place? [Select]Before switch S is in place, the brightness of bulb 3 is B3. What is the brightnessB3' of bulb 3 when the switch, S, is in place? [Select]B₁SB3B₂m
