Homework Answers
Diagram for center tapped transformer having two parts of secondary coil connected in parallel is shown below :
Voltage between X1 and X3 terminals is 0 because both terminals are at same potential having positive polarity.
Now voltage between X1 and X2 terminals = 240 V (Current =I)
Voltage between X3 and X4 terminals = 240 V (Current =I)
Voltage between X1 and X4 terminals = 240 V (Current =2*I)
It can be concluded that parallel connection of two coils will give same voltage at output terminals but current rating will increase due parallel connection of coils which is shown in figure.

RHODE ISLAND CORPORATION …… has two divisions, A and B, which manufacture bicycles. Division A produces the bicycle frame, and Division B assembles the rest of the bicycle. There is a market for both the bicycle frame produced by Division A, and the final product. Each division is treated as a profit center and have complete autonomy in setting transfer prices and in deciding how much, if any, units to produce. The transfer price for the bicycle frame has been...
