A series RL circuit includes a 5.55 V battery, a resistance of 𝑅 = 0.755 Ω, and an inductance of 𝐿 = 2.55 H. What is the potential difference 𝑉L(𝑡) across the inductor at time 𝑡 = 1.13 s after the circuit has been closed?

Step 1
13 s. We can use Ohm's Law to calculate the current in the circuit. Ohm's Law states that the current (I) is equal to the voltage (V) divided by the resistance (R). In this case, the voltage is 5.55 V and the resistance is 0.755 Ω. I = V / R I = 5.55 V / 0.755 Show more…

A resistor with R = 30.0 Ω and an inductor with L = 0.600 H are connected in series to a battery that has emf 50.0 V and negligible internal resistance. At time t after the circuit is completed, the energy stored in the inductor is 0.400 J. At this instant, what is the voltage across the inductor?
