Concept explainers

Microscopic view of current

In physics, the term current is expressed as the rate of flow of electric charges across the area per unit time (I=q/t). It propagates along in the direction of the motion of positive charges. When the current is caused by the motion of electrons, the direction of the current is opposite to the flow.

Question

Give me additional examples of values with infinite significant figures. According to our handouts, here is one of the examples: 3000 chocolate Bars which are considered countable numbers. Moreover, the final zeroes in a whole number are significant IF the unit of quantity is measurable like mass, temperature, length, current etc. Therefore, even the trailing numbers are counted as significant. Example: 40 kg (2 sig figs) & 1900 mm (4 sig figs). Give me more examples as well. Thank you!
