An Inductance L, Resistance R, and Ideal Battery of Emf $\varepsilon$

question 46

Multiple Choice

An inductance L, resistance R, and ideal battery of emf $\varepsilon$ are wired in series. A switch in the circuit is closed at time 0, at which time the current is zero. At any later time t the current i is given by:

• A) (\(\varepsilon\)/R)(1 - e^-Lt/R)
• B) (\(\varepsilon\)/R)e^-Lt/R
• C) (\(\varepsilon\)/R)(1 + e^-Rt/L)
• D) (\(\varepsilon\)/R)e^-Rt/L
• E) (\(\varepsilon\)/R)(1 - e^-Rt/L)
