Calculate the reactance of a 2 H inductor that is connected to a battery with peak voltage 10 V and angular frequency 40 radians/s.

The reactance is 80 Ω

Explanation:

Inductance H = 2 H

voltage v = 10 V

angular speed ω = 40 rad/s

The reactance of an inductive ac circuit   ωL

40 x 2 = 80 Ω

The current in the circuit is = V/ = 10/8 = 1.25 A

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
