太陽能板發電的問題(急)
我想用太陽能板發電,令燈膽發光,但唔成功,點解?
單晶太陽能板係2V 40mA
燈膽 1.5V
Thx!

將燈膽 1.5V 換去 LED 試試睇,不過我既可以令 LED 燈膽發光,就係暗佐少少。
if you want a light bulb to light up.
besides voltage, you have to consider the current.
40mA current is too small for a 1.5V light bulb to
light up.
i think you have to add several solar panels together
in series to increase the current.
you can take a try.
