What this template does

This is a ready-to-run GetCalcMaster Notebook starter. Open it into Notebook, run once with defaults, then tweak inputs and keep your assumptions next to the math.

How to use it (recommended)

Open in Notebook.
Enter Vin, R1, R2.
Compute Vout and divider current.
Try different R values to see sensitivity.
Record load assumptions (unloaded divider vs loaded).

Tip: When a result matters, verify it twice: a unit check + a second method (graph/estimate).

TEXT

# Voltage Divider

Unloaded divider formula:

**Vout = Vin · R2/(R1+R2)**

Also compute divider current: **I = Vin/(R1+R2)**.

Note: A load on Vout changes the effective R2.

MATH

Vin = 5

MATH

R1 = 10000

MATH

R2 = 20000

MATH

Vout = Vin * R2 / (R1 + R2)

MATH

I = Vin / (R1 + R2)
