2Ω Resistance Coil Pack Size_14 sized for the next step

sized for the next step up from the 100uA meter when small-signal circuits exceed its full-scale deflection

this 15-inch motion-converter model shows the engineering principle behind crankshaft pistons and rotary-to-linear mechanisms

supplying the plastic-coated counterpart to bare copper for circuit wiring where exposed conductor must be avoided

Seven hand-painted removable parts expose atria

2Ω Resistance Coil Pack Size_14 sized for the next stepTwo ohm reference coil non inductively wound from double silk covered constantan on a plastic rod, sealed inside a transparent tube with two terminals and plus or minus 1% precision.
