Ex 2 IL. 19. This rule can be used for all integers, both positive and negative 27. Impedance in an ac circuit plays the same role that resistance does in a dc circuit 28. Two parallel wires a distance of o apart carry the current i。 Ex3 IL. 7. This facilitates their use in circuit analysis
Ex. 2 II. 19. This rule can be used for all integers, both positive and negative. 27. Impedance in an ac circuit plays the same role that resistance does in a dc circuit. 28. Two parallel wires a distance of δ apart carry the current i. Ex.3 II. 7. This facilitates their use in circuit analysis
10. Here we must use wires one thousandth the diameter of a silk thread. 14. AC can be changed into DC, a process called rectification 16. An instrument for measuring current, voltage and resistance, the multi-meter is widely used in the work having connection with electricity. 19. This curve shows the fall in conductivity with increasing temperature

T. 1. The second law of motion provides a method for measuring shat is called the"inertial mass"of a body. All one needs to do is to apply the same force in turn to a standard of mass and to an un known mass and then to compare their accelerations, something that can be done anywhere in the universe with the same results No matter where we are, we can always tell a wooden ball from a lead ball of the same size by throwing them

2. **: male, born in 1938, professor, and advisor for doctoral students. He graduated from the Xi'an Military Telecommunications Engineering Institute in 1964 and remained there as a faculty member. He has long been engaged in the teaching and research in the field of radar. Through close cooperation with quite a few radar research institutes and enterprises. he has successively undertaken or taken charge of more than twenty national defence key preliminary research projects and engineering projects with many practical achievements, most of which have been popularized and applied, or used to equip the armed forces, thus ma king contributions to the development of radar technology in China
