two electric bulbs marked (25 w - 220 v and(100 w - 220 v are connected in series to
a 440 v supply which of the bulbs will fuse
a. 100 w.
6.25 w
c. none of this. d. both.

b. 25W

Explanation:

The 25W bulb has 4 times the resistance of the 100W bulb, so 4/5 of the circuit voltage will develop across that bulb. The 352 volts applied will far exceed the rating of the 25W bulb, causing it to fail.

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

c. magnitude and direction
