When the switch is closed,
A. the current will decay exponentially & the voltage will increase exponentially
B. the current will increase exponentially & the voltage will decay exponentially
C. the current will fall to zero & the voltage both will decay exponentially
D. the voltage and the current both remain constant
Answer:A
When the switch is closed,
A. the current will decay exponentially & the voltage will increase exponentially B. the current will increase exponentially & the voltage will decay exponentially C. the current will fall to zero & the voltage both will decay exponentially D. the voltage and the current both remain constant
Explanation: Instant switch is closed, the current is minimum zero than starts to increase till it reaches a constant value Vs/R, whereas voltage starts to reduce from Vs to 0 (Inductor Charging). 6. In the figure shown below,
