The unit of the quotient of inductance and resistance is called the time constant.
what is time constant?
The time constant τ (tau),is measured by T=L/R,in seconds,where R is the value of resistor in ohms and L is the value of inductor in Henry.
When a current is applied to an inductor it takes some time for the current to reach its maximum value, after which it will remain in a "steady state" until some other event causes the input to change. The time taken for the current to rise to its steady state value in an LR circuit depends on:
The resistance (R)
This is the total circuit resistance, which includes the DC resistance of the inductor (RL) itself, plus any external circuit resistance.
The inductance (L)
Which is proportional to the square of the number of turns, the cross sectional area of coil and the permeability of the core.
The transient time of any inductive circuit is determined by the relationship between the inductance and the resistance. For example, for a fixed value resistance the larger the inductance the slower will be the transient time and therefore a longer time constant for the LR series circuit. Likewise, for a fixed value inductance the smaller the resistance value the longer the transient time.

Answer:
It decreases
Explanation:
Wavelength and frequency has an inverse relationship. An inverse relationship is where one variable increases the other decreases and vice versa.
Answer: The Answer is A
Explanation: The most noticeable feature of the periodic table is that it is arranged as a chart with seven rows and eight columns, although the number of columns increases toward the bottom of the chart. Chemists refer to each row as a period and each column as a group. Each element in a period has the same ground state, and the elements become less metallic as you move from left to right. Elements in the same group have different ground states, but they have the same number of electrons in their outer shells, which gives them similar chemical properties.
