Answer:
The output power is 5.88 W.
Explanation:
We have,
Efficiency of CFL bulb is 0.42
Input power is 14 W
It is required to find the output power. The ratio of output power to the input power is called efficiency. It is given by :
[tex]\eta=\dfrac{P_o}{P_i}[/tex]
[tex]P_o=\eta\times P_i\\\\P_o=0.42\times 14\\\\P_o=5.88\ W[/tex]
So, the output power is 5.88 W.
