Question
Q6. A. With the aid of delta and star connection diagrams, state the basic equation from which delta – star – delta conversion equation can be derived.
B. Three batteries A, B and C have their negative terminals connected together, between the positive terminals of A and B there is a resistor of 0.5 ohm and between B and C three is a resistor of 0.3 ohm,
i. Battery A 105 V, Internal resistance 0.25 ohm’
ii. Battery B 100 V, Internal resistance 0.2 ohm
iii. Battery C 95 V, Internal resistance 0.25 ohm
Determine the current values in the two resistors and the power dissipated by them.
