Document Summary

We use a short-hand notation for variable values that have an exponent. For example, 100e3 w is usually written as 100 kw, where k signifies multiplication by 1000. In this course, we use m=1e6, k=1e3, m=1e-3, =1e-6 and n=1e-9 most often. When using any version of spice, the program is case-insensitive, i. e. there is no difference between m and m. spice uses meg for capital m, and u for the greek . If both i and v are positive as shown, the element is absorbing power, i. e. p = i*v > 0 i through variable across variable v. Fill in the following table for 5 different measurement possibilities. The textbook defines basic variables as charge (q), energy (w), and magnetic flux linkage ( ); then it derives the important circuit applied variables from them as current (i), voltage (v) and power (p).
