According to voltage divider rule: V L = RL*VS /( RL +RS ) the formula in the picture
1. Are the results identical using 1k Ohms and 100 Ohms as RL? Why?
2. I am wonder that can I use this method to measure the Rs of the microphone or the power supply or the batteries?
if can , how to implement it
thank you
