The initial current through the inductor is zero. When the switch (shown in green) is closed, then the current through the inductor
A. decreases from Vs/R to 0
B. increases from zero to Vs/R
C. decreases from Vs/L to 0
D. increases from zero to Vs/L
Answer:A
The initial current through the inductor is zero. When the switch (shown in green) is closed, then the current through the inductor
A. decreases from Vs/R to 0 B. increases from zero to Vs/R C. decreases from Vs/L to 0 D. increases from zero to Vs/L
Explanation: Current increases from zero to maximum value gradually due to the L nature. The KVL when switch is closed gives,
