    Worked examples

    R1 resistance (Ω): 100, R2 resistance (Ω): 200

    Series resistance: 300 Ω

    Using these sample input values gives the first labelled output above. Ideal resistors; tolerance, thermal limits and frequency response are not included.

    Questions & answers

    Can I use the default numbers for purchasing or safety certification?

    No. Replace the examples with your real values. Ideal resistors; tolerance, thermal limits and frequency response are not included.
