The resistance to be connected in series with each thyristor so that the current through the combination is 700 A and each of them is fully loaded is ___________(in mΩ)
A 200 A thyristor is to be operated in parallel with a 300 A thyristor their on state voltage drops are 1.5 V and 1.2 V respectively. What is the value of resistance to be connected in series with each thyristor so that the current through the combination is 500 A and each of them is fully loaded. ____ (in Ω)
It is required to operate 150 A SCR in parallel with 250 A SCR with their respective ON-State voltage drop of 1.2 V and 0.8 V. Calculate the value of resistance to be inserted in series with each SCR so that they share the total load of 400 A in proportion to their current ratings.___(in Ω)
