Since, n_i = 5

n_f = 2

This transition gives rise to a spectral line in the visible region of the Balmer series.

In philosophy, idealism is a diverse group of metaphysical views which all assert that "reality" is in some way indistinguishable or inseparable from human perception and/or understanding, that it is in some sense mentally constituted, or that it is otherwise closely connected to ideas. The definition of idealism is believing in or pursuing some perfect vision or belief. An example of idealism is the belief of people who think they can save the world.

Consumer equilibrium using utility approach

Posted by Ajaz Hussain 5 years, 3 months ago

CBSE > Class 11 > Economics

1 answers

Meghna Thapar 5 years, 1 month ago

When consumers make choices about the quantity of goods and services to consume, it is presumed that their objective is to maximize total utility. In maximizing total utility, the consumer faces a number of constraints, the most important of which are the consumer's income and the prices of the goods and services that the consumer wishes to consume. The consumer's effort to maximize total utility, subject to these constraints, is referred to as the consumer's problem. The solution to the consumer's problem, which entails decisions about how much the consumer will consume of a number of goods and services, is referred to as consumer equilibrium.

Meghna Thapar 5 years, 3 months ago

A budget line shows combinations of two goods a consumer is able to consume, given a budget constraint. An indifference curve shows combinations of two goods that yield equal satisfaction. To maximize utility, a consumer chooses a combination of two goods at which an indifference curve is tangent to the budget line. Budget line is a graphical representation of all possible combinations of two goods which can be purchased with given income and prices, such that the cost of each of these combinations is equal to the money income of the consumer.
