Draw a circuit with resistors in parallel and in series.
Use Ohm’s law to calculate the voltage drop across a resistor when current passes through it.
Contrast the way total resistance is calculated for resistors in series and in parallel.
Explain why total resistance of a parallel circuit is less than the smallest resistance of any of the resistors in that circuit.
Calculate total resistance of a circuit that contains a mixture of resistors connected in series and in parallel.
The information presented in this section supports the following AP® learning objectives and science practices:
4.E.5.1 The student is able to make and justify a quantitative prediction of the effect of a change in values or arrangements of one or two circuit elements on the currents and potential differences in a circuit containing a small number of sources of emf, resistors, capacitors, and switches in series and/or parallel.
(S.P. 2.2, 6.4)
4.E.5.2 The student is able to make and justify a qualitative prediction of the effect of a change in values or arrangements of one or two circuit elements on currents and potential differences in a circuit containing a small number of sources of emf, resistors, capacitors, and switches in series and/or parallel.
(S.P. 6.1, 6.4)
4.E.5.3 The student is able to plan data collection strategies and perform data analysis to examine the values of currents and potential differences in an electric circuit that is modified by changing or rearranging circuit elements, including sources of emf, resistors, and capacitors.
(S.P. 2.2, 4.2, 5.1)
5.B.9.3 The student is able to apply conservation of energy (Kirchhoff’s loop rule) in calculations involving the total electric potential difference for complete circuit loops with only a single battery and resistors in series and/or in, at most, one parallel branch.
(S.P. 2.2, 6.4, 7.2)
Most circuits have more than one component, called a
resistor that limits the flow of charge in the circuit. A measure of this limit on charge flow is called
resistance . The simplest combinations of resistors are the series and parallel connections illustrated in
[link] . The total resistance of a combination of resistors depends on both their individual values and how they are connected.
Resistors in series
When are resistors in
series ? Resistors are in series whenever the flow of charge, called the
current , must flow through devices sequentially. For example, if current flows through a person holding a screwdriver and into the Earth, then
in
[link] (a) could be the resistance of the screwdriver’s shaft,
the resistance of its handle,
the person’s body resistance, and
the resistance of her shoes.
[link] shows resistors in series connected to a
voltage source. It seems reasonable that the total resistance is the sum of the individual resistances, considering that the current has to pass through each resistor in sequence. (This fact would be an advantage to a person wishing to avoid an electrical shock, who could reduce the current by wearing high-resistance rubber-soled shoes. It could be a disadvantage if one of the resistances were a faulty high-resistance cord to an appliance that would reduce the operating current.)

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
