Selection of cells

  1. Leclanche cell for intermittent supply of current.
  2. Daniel cell for constant EMF source.
  3. Lead accumulator for strong current ~ 100 A due to its low r.
  4. Lead accumulator also called acid cell for highest EMF (= 2.05 V) & minimum internal resistance (≈0.01 Ω).
  5. Dry cell for weak current ~ 10 mA.
