    Physics, Chemistry and Biology: Post your doubts here!

    But if S1 was closed...then without doubt both lamps would be on as the current would flow through the base current in the transistor so the circuit would be complete...if s1 was open no current would flow throughout to the base in the transistor so the circuit wont be complete...both lamps...

    yeah but.. I got the answer as 7.5% non recurring. Many of my other friends got 16.33 recurring as some of you said earlier...but remember in the question it was given that. The area of 1 solar panel is 8m^2 so the total area of Both solar panels is 16m^2. The diagram showed 2 solar panels...

    Physics P3.. how was it?

    Hey guys so can anyone just tell me wether in that solar panel question in 32 they said the area for ONE panel was 8m square or area for BOTH was 8m square?? Please someone tell me guys!
