Question

in which size class the teacher prepared the electric circuit using battery bulb wires keys add notice that the bulb did not light up what are the possible causes for the bulb not to light up
(A) the wiring joints are loose
(B) the bulb may be fuse
(C) cell is not working
(D) all of the above
​

Answer 1

Answer:

d part all of these

Step-by-step explanation:

ans is surely correct

Answer 2

Step-by-step explanation:

Suppose that you were given a small light bulb, an electrochemical cell and a bare copper wire and were asked to find the four different arrangements of the three items that would result in the formation of an electric circuit that would light the bulb. What four arrangements would result in the successful lighting of the bulb? And more importantly, what does each of the four arrangements have in common that would lead us into an understanding of the two requirements of an electric circuit?

The activity itself is a worthwhile activity and if not performed before, one ought to try it before reading further. Like many lab activities, there is power in the actual engagement in the activity that cannot be replaced by simply reading about it. When this activity is performed in the physics classroom, there are numerous observations that can be made by watching a class full of students eager to find the four arrangements. The following arrangements are often tried and do not result in the lighting of the bulb.
