You have been asked to investigate the loading effects on an alternator supplying a load and also charging a car battery at the same time. The output of the alternator has been rectified to smooth dc, and the circuit is shown below. Using Kirchhoff analysis, determine the initial current in each section along with its direction and the potential difference across the load.

Suppose a digital thermometer works by measuring the voltage across a thermistor (a resistor that is heated or cooled by contact). The thermistor has a temperature coefficient of a = 0.032 °C-1 and reference resistance of 2.6 N at 20 °C, and is part of a circuit designed such that 29.1 mA of current passes through, regardless of the resistance of the thermistor. How precise* must the voltage measurement of the thermistor be such that the thermometer can detect changes of 0.1 °C? Give your answer in units of mV, and you can assume that the thermistor's dependence on temperature is linear. *1.e., What is the difference in voltage measurements between temperature measurements of, e.g., 37.0 and 37.1 °C?
Suggest and draw a battery charging electronic circuit consisting of two silicon- controlled rectifiers (SCR1 and SCR2) and two diodes. The charging of battery is to be controlled by SCRS' triggering angles. Your suggested circuit must include a current limiting resistor.
