You definitely need to be given the frequency. Both L and C have impedances which are dependent on frequency.chemistrymole said:Homework Statement
A series RLC circuit contains 4.2 ohm resistor, a 42mH inductor and a 22 microfarad capacitor. it is powered by a 120 V (rms) alternating current. what is the total impedance (Z) of the circuit?
I think I need to assume the Hz which is 377 Hz and then convert into 377/2pi which is cyclic Hz I get 60Hz. The problem does not give this. Am I suppose to assume this? Otherwise I cannot use the formula such as XL=wL and so on.
Does anyone see a different route to find Z.

An RLC circuit problem refers to a type of electrical circuit that consists of a resistor (R), an inductor (L), and a capacitor (C). These components are connected in series or in parallel and the circuit is powered by a voltage source. RLC circuits are commonly used in electronics and are important for studying the behavior of electrical circuits.
To solve an RLC circuit problem, you can use a variety of techniques such as Kirchhoff's laws, Ohm's law, and the equations that govern the behavior of resistors, inductors, and capacitors. You will need to use a combination of these techniques to determine the current, voltage, and other properties of the circuit.
RLC circuits have many practical applications, such as in AC power systems, audio equipment, radio communication, and electrical filtering. They are also used in electronic devices to control and stabilize the flow of electricity.
The behavior of an RLC circuit is affected by several factors, including the values of the resistor, inductor, and capacitor, the frequency of the power source, and the type of circuit (series or parallel). The properties of the components, such as resistance, inductance, and capacitance, also play a role in determining the behavior of the circuit.
Some common problems encountered in RLC circuits include resonance, where the circuit responds strongly to a specific frequency, and damping, where the circuit's oscillations decrease over time. Other issues may include the breakdown of components, incorrect values of components, and incorrect circuit configurations.
