Time Constant for an RLC circuit

Click For Summary
SUMMARY

The time constant of an RLC (Resistor, Inductor, Capacitor) circuit is a critical parameter that determines the response time of the circuit to changes in voltage or current. In a series RLC circuit, the time constant is influenced by the resistance and inductance, while in a parallel RLC circuit, it is affected by the resistance and capacitance. The time constants differ between series and parallel configurations, impacting the transient response of the circuit. Understanding these differences is essential for analyzing the current and voltage behavior in RLC circuits.

Nope, sorry. We don't give out answers to schoolwork questions here on the PF.

What can you tell us about RLC circuits? Is it a parallel or series RLC circuit? Would the time constants be different for parallel versus series?

How would you go about deriving the current and voltage behavior or an RLC circuit?
 
I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
