An electric current flowing in a conductor always produces a magnetic field. True false Transformers step voltages UP when going from the primary to the secondary side True False The CREZ lines in Texas are the highest voltage used in the electrical grid. True False

Solution

29) an electric current flows through a conductor always produce a magnetic field perpendicular to the current propagation. Thus answer is true

30) transformers are two types 1. stepup 2. step down..... As we can use any thing accordingly our requirement. Thus it is not necessary that every time it should be stepup only. Thus answe is false

31) yes the crez lines in texas are the highest voltage used in electrical grid. Answer is true
