Answer:
The power dissipated is 45W.
Step-by-step explanation:
The power
varies jointly with resistance
, and the square of current
:
,
where
is the constant of proportionality.
Now we are told that when
and
,
:
![15 = \alpha (1A)^2*15\Omega](https://tex.z-dn.net/?f=15%20%3D%20%5Calpha%20%281A%29%5E2%2A15%5COmega)
solving for
we get
,
which gives
![P = I^2R](https://tex.z-dn.net/?f=P%20%3D%20I%5E2R)
With the value of
in hand, we find the power dissipated when
and ![I = 3 A:](https://tex.z-dn.net/?f=I%20%3D%203%20A%3A)
![P = (3A)^2(5\Omega )](https://tex.z-dn.net/?f=P%20%3D%20%283A%29%5E2%285%5COmega%20%20%29)
![\boxed{P =45W}](https://tex.z-dn.net/?f=%5Cboxed%7BP%20%3D45W%7D)
Thus, the power dissipated is 45W.
