About Direction of current in the inductor in RL circuits

Click For Summary
SUMMARY

The discussion centers on the behavior of current direction in inductors within RL circuits. It clarifies that during the charging phase at time t(0-), the voltage drop across the inductor aligns with the initial current direction. Conversely, at time t(0+), the discharging current flows in the opposite direction of the initial current, contrary to the behavior observed in capacitors. This distinction is crucial for understanding inductor voltage behavior as the circuit approaches steady-state conditions.

i'm a bit confused about the direction of current in the inductor in RL circuit, i thought in the charging stage at t(0-) the the voltage drop on it will be in the direction of the initial current, which means the discharging current at t(0+) will be in the opposite direction of the initial current (voltage rise direction) as in the case of the capacitors, but i find the oppoaite in the books.
so could anyone explain this please...

Welcome to PF mazen_zone.

Here's a wiki page that might help. http://en.wikipedia.org/wiki/RL_circuit#Time_domain_considerations"
...the inductor will only have a voltage across as long as the current in the circuit is changing — as the circuit reaches its steady-state, there is no further current change and ultimately no inductor voltage.
