A. The digestive and excretory systems interact to produce and remove waste from the body.
B. The circulatory and digestive systems interact to produce and deliver oxygen to the body.
C. The respiratory and digestive systems work together to produce and transport nutrients to all cells in the body.
D. The immune and digestive systems work together to provide protection against infectious organisms in the body.

Act has a 1200: 5 or 240: 1 turns ratio. it is short circuited. what is the maximum current at 1200a primary if we put a 100ohm resistor across the secondary end of the ct. use it as current source circuit.
