Forward Voltage Triggering
If Va is increased the collector to emitter voltages of both transistor are also increased. Hence the leakage current at J2 increase. This leakage current is the collector current of transistor Tr2. It means with the increase in IC2 IC1 Increased any this causes α1 + α2 tends to unity which is responsible to turn on the thyrisotr.
Electrical energy If the power is measured in watts and the time in seconds then the unit of energy is watt- seconds or Joules.
