Question 3

A solar cell on a low-power environmental monitoring sensor charges a 6.0 μF6.0\ \mu\text{F}6.0 μF capacitor for 50 s50\ \text{s}50 s with a constant current of 12 μA12\ \mu\text{A}12 μA.

What is the energy transferred to the capacitor?

1.5×10−2 J1.5 \times 10^{-2}\ \text{J}1.5×10−2 J

3.0×10−2 J3.0 \times 10^{-2}\ \text{J}3.0×10−2 J

6.0×10−2 J6.0 \times 10^{-2}\ \text{J}6.0×10−2 J

1.2×10−1 J1.2 \times 10^{-1}\ \text{J}1.2×10−1 J
