For this Wheatstone Bridge based NTC temperature measurement circuit, which is the lowest voltage measurement (VAB) that is possible to obtain at 60ºC? (NTC B: 3435 +/-1%) Give answer in Volts rounded to two decimal points.

You have an electric car with these specifications:

• ten 12V batteries
• constant velocity of 80 km/h
• flat road (friction 1.2kN -> aerodynamic load included)

Your head of powertrain has found a battery cell with excellent specifications and yet cheap. He decides upon a 142s2p accumulator configuration using the cells with a capacity of 5.8 Ah. The manufacturer specifies an internal impedance of 1.5 mOhm. However, after a while you notice the cells are of horrible quality and their real capacity varies significantly leading to an unbalanced accumulator.

He performed experiements to find an approximation of the cells SoC relation to their open-circuit voltage (EMF) as shown in the following figure:

Assume due to imbalance, exactly half of the accumulators cells are at 40% SoC and half at 80% SoC. What current will be drawn at the maximum allowed power usage? Give answer in Amps to nearest whole number
