Did you know?
Web\$\begingroup\$ Notice that for a simple RL circuit at steady-stade the final current is I = V/R because L is short at DC. Thus larger resistance value will decrease the "charging" time (transient time). Because the end current is smaller due to large resistance. Do you see it? And this why L/R is true. \$\endgroup\$ – WebIn an \( L R \)-circuit, the time constant is that time in which current grows from zero to the value (where \( I_{0} \) is the steady-state current)📲PW App...
