Voltage Divider Example # 1: A Large Resistor of 10 Mohm with a small Resistor of 5 ohm

We previously learnt the basic voltage divider formula. In this post, you'll learn how voltage is divided when a very large resistor connects in series with a very small resistor.

Statement: A 10 MΩ resistor connects in series with a 5 Ω resistor, the input source is a 15 V battery. Apply VDR to find the voltage across 10 Mohm resistors.

Solution:

After going through above example, one can understand that almost all voltage dropped across the large resistor.
