The sun delivers $10^3 W/m^2$ of electromagnetic flux to the earth's surface. |
The sun delivers $10^3 W/m^2$ of electromagnetic flux to the earth's surface. The total power that is incident on a roof of dimensions 8m x 20m, will be: |
6.4 x 103W 3.4 x 104W 1.6 x 105W None of these |
1.6 x 105W |
$ \text{ Total power is } P = IA = 10^3 \times 160 W = 1.6\times 10^5W$ |
