By using delta/star transformation for
figure 40 above, find the current supplied by the battery.
figure 40 above, find the current supplied by the battery.
Solution
To simplify the circuit, reduce the
delta ABC in figure 40 above by its equivalent star as shown in figure 41
below.
delta ABC in figure 40 above by its equivalent star as shown in figure 41
below.
Upon further simplification, figure 41
becomes as shown in figure 42 below.
becomes as shown in figure 42 below.
For figure 42 above, total circuit
resistance
resistance
= 20.6 + 6 + 5 = 31.6Ω
Hence,
I = 30/31.6 = 0.95A
I = 30/31.6 = 0.95A
