Extracted text: Review | Constants Reset Help The three bulbs in (Figure 1) are identical. All are glowing. series Suppose each bulb has resistance R. With bulb C in place, bulbs B and C are in and parallel have equivalent resistance increases Bulb A is in with B and C, and the total resistance of the circuit is decreases With bulb C removed, bulbs A and B are in with total resistance brighter dimmer Removing bulb C the total resistance and thus the current from the Figure < 1="" of="" 1=""> battery. R 2 All the battery current passes through bulb A, so bulb A gets R 3R Bulb B no longer has to share current with bulb C, so the current through bulb B and A 2 bulb B gets 2R With bulbs A and B in series, the brightness of bulb A has to be the brightness of bulb greater than В. В less than the same as
