Att= 0, a 9.9 v battery is connected to aseries circuit containing a 15 ω resistor and a0.9 h inductor. what will be the current in the circuit, along time after the circuit is established? answer in units of a.040 (part 2 of 2) 10.0 pointshow long will it take the current to reach50 percent of its final value? answer in units of s.

Answer

given,

battery voltage = 9.9 V

resistance of the circuit = 15 Ω

Inductor  = 0.9 H

a) current

I = 0.66 A

b) Time taken to reach current to 50%

taking log both side

t = τ ln 2

t  = 0.0416 s

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
