(surtch ) Consider the Circuit below: RI=200r a 7. R2 35mH 1000 For parts a-c assume the switch S is in position "a" after it was off for a long time. a) Find the time constant t for the switch in position "a". b) Determine the maximum inductor current, Imax. c) When will the inductor current be 95% of Imax. For parts d-f assume the switch S is in position “b" after it was in position "a" for a long time d) Find the time constant t for the switch in position "b". e) When will the inductor current be 5% of its initial value (initial value is when the switch is switched from “a" to “b") f) How much energy is dissipated by the resistance if the switch is in position "b" for a long time. eele

Please in typing format please ASAP for the Please I will like it please ASAP for the

explain each step and show how to get to this answer please i do not undestand

Could I please have the answers and workings out to the question attached. Could you please write down any formulas used.

Assume that the initial energy stored in the inductors below is zero. Find the equivalent inductance withrespect to the terminals a, b.

Consider the circuit in figure given below: A B The capacitor C is initially charged. At time 0, the switch is connected from A to B and the voltage across the capacitor is measured. The following data are recorded by a data acquisition system: t(s) 0.0 0.1 0.2 0.3 0.4 0.5 V(V) 4.98 1.84 0.68 0.25 0.09 0.03 (a) Determine the linear correlation coefficient betweent and V. (b) Determine the linear correlation coefficient between t and In(V).

Need help steps would be helpful please and thank you!

SOLVE STEP BY STEP IN DIGITAL FORMAT A 12 volt battery is connected to a series circuit in which the inductor is 1/4 Henry and the resistance is 25 Ohm. Determine the current i, if the initial current is zero.

A 140-mH inductor and a 5.10-n resistor are connected with a switch to a 6.00-V battery as shown in the figure below. Wele R L (a) After the switch is first thrown to a (connecting the battery), what time interval elapses before the current reaches 220 mA? ms (b) What is the current in the inductor 10.0 s after the switch is closed? | A (C) Now the switch is quickly thrown from a to b. What time interval elapses before the current in the inductor falls to 160 mA? ms
