with the power equation and the potential difference equation
to obtain a relationship between power and resistance. |

| Rearrange
the equation and solve for the resistance in the filament of
a 150-W lightbulb. |
| (0.0K) |
| To
find the length of the filament, use the resistance formula
given. |

problem two, first find the length that 250 coils take up. |
| (0.0K) |
| Subtract
the length the coils used from one inch to give the total space.
Divide the total space by the number of coils to give the space,
s, between each coil. |
