• 22 Ohm, 1.5W resistor: most useful together with LEDs for TimingLight or tester equipment.
• 0.1 Ohm 5W resistor: most useful to connect instead of a wire where current measurement needed (upto 7A; connect 2 or more in parallel for higher current limits or lower voltage drop) through it. Also necessary when increasing flyback votlage, each diode-branch needs a small resistor in series so the branches can be connected in parallel. See diode.
