This module describes how to find the Thevenin and Norton
equivalent circuits of an RLC circuit and sources.
When we have circuits with capacitors and/or inductors as wellas resistors and sources, Thévenin and Mayer-Norton
equivalent circuits can still be defined by using impedances andcomplex amplitudes for voltage and currents. For any circuit
containing sources, resistors, capacitors, and inductors, theinput-output relation for the
complex amplitudes of
the terminal voltage and current is
with
.
Thus, we have Thévenin and Mayer-Norton equivalentcircuits as shown in
[link] .
Let's find the Thévenin and Mayer-Norton equivalent circuitsfor
[link] . The open-circuit voltage and
short-circuit current techniques still work, except we useimpedances and complex amplitudes. The open-circuit voltage
corresponds to the transfer function we have alreadyfound. When we short the terminals, the capacitor no longer
has any effect on the circuit, and the short-circuit current
equals
.
The equivalent impedance can be found by setting the source tozero, and finding the impedance using series and parallel
combination rules. In our case, the resistor and capacitor arein parallel once the voltage source is removed (setting it to
zero amounts to replacing it with a short-circuit). Thus,
.
Consequently, we have
Again, we should check the units of our answer. Note in
particular that
must be dimensionless. Is it?
Communication is effective because it allows individuals to share ideas, thoughts, and information with others.
effective communication can lead to improved outcomes in various settings, including personal relationships, business environments, and educational settings. By communicating effectively, individuals can negotiate effectively, solve problems collaboratively, and work towards common goals.

Every time someone flushes a toilet in the apartment building, the person begins to jumb back automatically after hearing the flush, before the water temperature changes. Identify the types of learning, if it is classical conditioning identify the NS, UCS, CS and CR. If it is operant conditioning, identify the type of consequence positive reinforcement, negative reinforcement or punishment
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills
hello. autism is a umbrella term. autistic kids have different disorder overlapping. for example. a kid may show symptoms of ADHD and also learning disabilities.
before treatment please make sure the kid doesn't have physical disabilities like hearing..vision..speech problem. sometimes these

sometimes due to these physical problems..the diagnosis may be misdiagnosed.
treatment for autism.
well it depends on the severity.
since autistic kids have problems in communicating and adopting to the environment.. it's best to expose the child in situations where the child

please consult a therapist to know what suits best on your child.
and last as a parent. I know sometimes it's overwhelming to guide a special kid.
but trust the process and be strong and patient as a parent.
