Rt L The electric current i in a circuit containing a resistance and an inductance see the figure below is given by In where I is the current at t 0 R is the resistance t is the time and L is the inductance Find how long in s it takes the current to reach 0 4 of the initial value of 0 751 A if 1 0 751 A R 7 61 2 and L 1 26 H E R The current changes from 0 751 A to 0 4 of 0 751 Ain Round to the nearest thousandth as needed S
