The comparator does not draw any appreciable current, otherwise it will interfere with the constant-current charging. Voltage is monitored across the capacitor and signals are generated when the voltage becomes equal to the voltage to be measured (V in) and the charging starts at zero volts. One of the voltage is the input voltage ( V in) and the other will be the voltage across the capacitor. This IC compares the two voltages and signals for which of the two voltages is larger. This section of control and gating is based on an integrated circuit called the Comparator. In electronics, It is called a ‘Clock’ which generates pulses generally achieved using 555 timer chip.įirst Aid Treatment in Electric Shock - Causes, Sources, Severity Voltage Control and Gating
