Q. |
The slope of the V-I curve of a solar cell is 66.1°. Calculate the value of resistance. Assume the relationship between voltage and current is a straight line. |
A. | 3.5 Ω |
B. | 2.2 Ω |
C. | 2.5 Ω |
D. | 2.9 Ω |
Answer» B. 2.2 Ω | |
Explanation: the slope of the v-i curve of a solar cell is resistance. the slope given is 66.1° so r=tan(66.1°)=2.2 Ω. the slope of the i-v curve is reciprocal of resistance. |
