Measure the diameter of the circle using ruler a and ruler b. given that the actual diameter of the circle is 2.264 cmcm, classify the following statements that describe the diameter measurement of the circle according to the ruler. drag the appropriate items to their respective bins.

Ruler A :

According to ruler A, the diameter of the circle has only one certain digit and one uncertain digit. if we look at measurement of a diameter, it contain two significant figures. so the certainty  of the diameter measurement is smaller.

Ruler B :

According to ruler B, the certainty  of the diameter measurement is greater. because it contain two certain and one uncertain digit. it has three significant figures.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
