A battery of silicon photocells mounted on a plane surface operates with an efficiency of 16.7%. It is installed at a location 45° north. The time is 10:00 on April 1, 2017. When the battery faces the sun directly, it delivers 870W to a resistive load. How much power does it deliver if the surface is set at an elevation of 25° and faces true east?

Activity 1: You are testing an electrical device which can be modelled by the figure shown below: 18 -j12 j6 8 -j10 i1 E1 12 13 E2 13 The above electric circuit can be characterized by the following equations: 1811 + j6(I1 – 2) + 4(I1 – I2) = 1020° -j121, + 8(12 – I3) + 20290° + 4(12 – 1) + j6(I2 – 1) = 0 -j1013 + 1313 – 20290° + 8(I3 - 12) = 0 1. Rearrange the above three equations. 2. Write the set of equations in matrix form (A.x = b) 3. Find the determinant of the resulted matrix (A).
