Identical light bulbs are connected to an EMF as shown. Assume the light bulbs are chmic and the EMF is ideal. What happens to the brightness of the bulbs when a short, S (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 brightness B₁' 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 brightness B3' of bulb 3 when the switch, S, is in place? [Select]
