A charger a battery and a load are connected in parallel. The voltage across the charger is 12.5 volts and the battery has an emf of 12 volts and internal resistance of 0.1 ohm. The load consists of a 2 ohms resistor. Find the current through the charger.
The circuit shown in Figure DP 3-11 is designed to
help orange growers protect their crops against frost by sounding
an alarm when the temperature falls below freezing. It contains a
thermistor that has a resistance Ro=620 N at the temperature
To=20 °C=293 °K and ß= 3330 °K. (See problem DP 3-9.)
The alarm will sound when the voltage at the - input of
the comparator is less than the voltage at the + input. Using
voltage division twice, we see that the alarm sounds whenever
