# The switch S in Figure 20.27 is closed at t = 0 and the current at a reference time t ref &gt; 0 is I ref . If the circuit is changed as, described below and the switch is again dosed at t = 0, determine whether the current I at the same time would be greater than, less than, or equal to the original value of I ref . Indicate your answers wilt G. L. or E, respectively. (a) Both the battery voltage ε and the resistance R are doubled. (b) The inductance L b doubled. (c) The battery voltage ε . the resistance R , and the inductance L are each doubled. Figure 20.27 A series RL circuit. As the current increases toward its maximum value, the inductor produces an emf that opposes the increasing current.
