Solution

The output voltage can be found using the formula for a voltage divider, which is:

Vout = Vin * (R2 / (R1 + R2))

Substituting the given values into the formula, we get:

Vout = 35mV * (235kΩ / (950Ω + 235kΩ))

First, let's convert the resistances to the same units for easy calculation. 1kΩ is equal to 1000Ω, so 235kΩ is equal to 235000Ω.

So, the formula becomes:

Vout = 35mV * (235000Ω / (950Ω + 235000Ω))

Adding 950Ω and 235000Ω gives 235950Ω.

So, the formula becomes:

Vout = 35mV * (235000Ω / 235950Ω)

Performing the division gives approximately 0.99596.

So, the formula becomes:

Vout = 35mV * 0.99596

Multiplying 35mV by 0.99596 gives approximately 34.8586mV.

So, the output voltage Vout is approximately 34.8586mV.
