Question

Gauge At Dash Tank Unit Full Position (High Resistance) Empty Position (Low Resistance) il Wiring Connector (Full) O Float Positions (Empty) Ignition Switch Battery TPM-9983 Figure 1-Fuel Gauge Schematic Wiring Diagram

A simple electric motor consists of a cylindrical armature with a coil around it. A battery feeds current into the coil and this produces a magnetic field around the it and so the armature became an electromagnet. The magnetic field interacts with the armature that generate a rotation. The commutator can change the direction of the current every half-turn. This component can reverse the north and the south poles of the armature and it create a rotation.   

QUESTION

1. Create a formula for that system!

input: fuel level, output: pointer deviation

Answer 1

Sol we replace coils by appropriate resistances let us denote fuel level by = K• Max where o<KK 1 & Max = maximum af fuel level So for any k linel Root = K. Root Is = D. Vb . Re, + K. Rpot Rez - Rest K Rpot desiation = c. (IRE- I Rez) Stact =Icl.1- KR pat K Roat + Road c. Rca V6 Reit Rea + kRpot (Rest Rez) Pointes

let the binter deniation be from. O at kao P.D. (pointes deviation) at ko L = c Rc, V6 RC, ther) (it Root) { 873 c = to (Rethez) * (1th pot) - Now for c = n RCO V any intermediate k P.D = 6L. (Roth c2 x (1th pot) x RC2 VG Revb Merethe) Ce+ KRport = L(it Root) 1+ KRpot. PD fuel level ilp o/p = k = P.D
