- A Coil With A Resistance Of R And Self Induction L Is Connected To A Voltage Source V How Long After The Circuit Is Cl 1 (30.15 KiB) Viewed 30 times
A coil with a resistance of R and self induction L, is connected to a voltage source V. How long after the circuit is closed does the current in the circuit reach 90 percent of its final value and how much energy is stored in the magnetic field at that moment? Select one: O a. 1 = In (10): U = L (0.9%) ² t t = LRIn(10); U = L = -(0.11) ² 1-In (3) ; U = L (09) ² t = L R O d. t = ln(10) —; U = L (0.9VR) ² R e. 2 L = In (10) ; U = L (0.9) ² R O b. OC. O
