Question

A conducting bar can slide freely at a velocity u=20ay m/s and b=4az mwb/m2 over two conducting rails with length of separation 6cm. The induced voltage is: (bold entities refer to vector quantities) a. -3.8 mv b. 3.8 mv c. -4.8 mv d. 4.8 mv

Answer 1

. The voltage range of +-10 % of the nominal voltage defined in EN 50160 has to be guaranteed by the utility only in 95 % of the 10 minute average values. Incidents which are shorter than 10 minutes cannot be avoided and may not be criticized.
