If the meter is set to read DC voltage in the 20 volt range and it displays a 1 then it should mean 1 volt assuming that the maximum reading would be 20 volts at that setting. But if it is only around 1 volt is might be more accurate to set it at say 2V range to get say 1.6 actual volts.
Answer:
The energy source that does not use heat in the process of converting it to electricity is;
c. Sunlight
Explanation:
In converting Sunlight energy source to electricity, the photons in the light from the Sun excite electrons in the solar cells silicon layers, such that the electrons travel from n-type silicon layer to the p-type silicon layer creating electric potential energy that does work as the electrons flow back in the form of electricity from the p-type to the n-type silicon layer through an external circuit
