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.
