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.)
is it possible to leave every good at the same level
Joseph
I don't think so. because check it, if the demand for chicken increases, people will no longer consume fish like they used to causing a fall in the demand for fish

is not really possible to let the value of a goods to be same at the same time.....
Salome
Suppose the inflation rate is 6%, does it mean that all the goods you purchase will cost
6% more than previous year? Provide with reasoning.
Not necessarily. To measure the inflation rate economists normally use an averaged price index of a basket of certain goods. So if you purchase goods included in the basket, you will notice that you pay 6% more, otherwise not necessarily.
Good day
How do I calculate this question: C= 100+5yd G= 2000 T= 2000 I(planned)=200.
Suppose the actual output is 3000. What is the level of planned expenditures at this level of output?

money as unit of account means what?
Kalombe
A unit of account is something that can be used to value goods and services and make calculations
Jim
all of you please speak in English I can't understand you're language

I want to know how can we define macroeconomics in one line
Muhammad
it must be .9 or 0.9
no Mpc is greater than 1
Y=100+.9Y+50
Y-.9Y=150
0.1Y/0.1=150/0.1
Y=1500

hi can someone help me on this question
If a negative shocks shifts the IS curve to the left, what type of policy do you suggest so as to stabilize the level of output?
discuss your answer using appropriate graph.
