Need with detail explanation of step by step solution i will upvote u

8. 96 electric detonators, having a 2.3 2/det. resistance, are connected with 50m of connecting wires of 0.03 (2/m resistance and 200m of firing and bus wires with a total calculated resistance of 2 0 for both bus and firing wires. The optimum number of parallel circuits are: A. 12. B. 8. C. 6. D. 4. E. None of the answers. 9. 48 electric detonators of 2.4 Q/det are connected in 6 identical parallel circuits. 50 m connecting wires show a total resistance of 0.165 ( and 100 m of both firing and bus wires show a total resistance of 0.3 2 (ohm). The calculated Current per detonator is A. & amps when using a 220 Volt AC-power source. B. 10 amps when using a 220 Volt AC-power source. C. 1.9 amps when using a 220 Volt AC-power source. D. 45.8 amps when using a 110 Volt AC-power source E.
