Question

when you are solving for first order circuits, how can youfind Req of the circuit? do you solve it when a switch is closed oropen? in the first order ciruict, when the swtich closes it becomesshort circuited. when solving for the first order circuits, how do you know when to short-circuit a resistor/voltagesource when the switch closes (parallel to it, series toit,etc.)? when you are solving for first order circuits, how can youfind Req of the circuit? do you solve it when a switch is closed oropen? in the first order ciruict, when the swtich closes it becomesshort circuited. when solving for the first order circuits, how do you know when to short-circuit a resistor/voltagesource when the switch closes (parallel to it, series toit,etc.)?

Explanation / Answer

for calculating Req of the circuit you just short circuit all thevoltage source and open circuit all the current source, and justfnd out Rth, its the Req of the circuit. yes in first order circuitt when switch close its becomes shortcircuit if switch is in parallel of theresistor/voltage source.
