Can social welfare be measured by "adding up" peoples’ utilities? Why or why not? If not by using utility, how can policy makers estimate the welfare of government policies?

Social welfare can be measured by adding up the utilities of people when the benefits are distributed in such a way that no person derives utility at the cost of another person.

It should be noted that social welfare systems give assistance to people through programs such as health care, unemployment compensation, food stamps, child care assistance, etc.

The government can estimate the welfare of government policy through interpersonal comparison of utility.

Social well-being can be measured by the "sum" of public services provided to people.

Explanation:

A government, as well as policy makers, that promote efficient public policies aiming at the positive social and economic promotion of its population is promoting social welfare and the degree of that social welfare can be measured by the "sum" of the public services provided.

This is because public services, when performed in efficient ways, allow for the reduction of the needs of a society. A community that has all its needs met is a society with a high degree of social well-being, which can achieve very beneficial and uplifting standards of living.

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.
