Assignment:
In the circuit E=60V, R_1=40 Ohms, R_2=25 Ohms and L=0.3H. Switch S is closed at t=0 s. Just after the switch is closed
a) What is the potential difference across the resistor R_1?
b) Which point (a or b) is at higher potential?
c) Find potential difference across the inductor (L).
d) Which point is at higher potential (c or d)?
e) What is the maximum value for current through R_2 and how much time is needed to reach half of that maximum value?
