Circuit tools
Calculate. Open the circuit. Keep going.
Start with a practical calculation, inspect the assumptions and continue in the editor with an editable schematic and real SPICE simulation.
Loaded voltage divider
Size a divider for the voltage you need with the actual load attached. See loading error, current and resistor dissipation.
Open toolRC low-pass filter
Choose a cutoff frequency and resistor. Calculate the capacitor, select standard values and open a circuit ready for AC simulation.
