Calculation method
Calculation method
Unloaded output (V)
a × c ÷ (b+c)
Divider current (A)
a ÷ (b+c)
Symbols and units
- a
- Supply voltage (V)
- b
- Upper resistance (Ω)
- c
- Lower resistance (Ω)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- The output is across the lower resistor. Loading by another circuit is excluded.
