Answers

  • Your question has some difficulties in symbols and variables to read. That's why I am re-writing (re-arranged) the Question's statement again which is:

Question:

For the R-C circuit shown in figure 1 on page 3, R= 100 ohms and C=1.00F.

A)What is the time constant of the R-C circuit?

B) consider that the capacitor is initially not charged and the voltage of the battery is 3.00 V. The switch is closed at t=0. Using the appropriate formulas, write down the voltage Vc(t) on the capacitor and the current I(t) in the circuit.  

C) consider that the capacitor is initially fully charged to 3.00 V. The switch is open at t=0. Using the appropriate formulas, write down the voltage Vc(t) on the capacitor and current I(t) in the circuit.

  • Your Question is missing the figure as well, which is attached below, please find it in the attached file.

Answer:

Part.A

100 seconds

Part.B

Vc(t)=0V

I(t)=30mA

Part.C

Vc(t)=3.0V

I(t)=0A

Explanation:

Given Data:

Resistance=R=100 ohms

Capacitance=C=100F

Part.A: Time constant=T=?

Time constant:

Time required to charge the capacitor upto 63.23% of the applied voltage is called a Time constant.

As we know that time constant for the RC (circuit having only resistor and capacitor) is equal to product of resistance and capacitance

T=R*C

so T=100*1

T=100seconds

Part.B: Vc(t) and I(t)=? If switch is closed

Given Data:

Voltage of the battery=Vs=3.0V

Capacitor is not charged initially and switch is closed at t=0 means that the circuit will become short (because capacitor is charging) in which current I(t) exist and voltage Vc(t) is zero.

Short circuit:

The circuit in which current is maximum and voltage is zero.

Thus voltage on the capacitor is Vc(t)=0V

Now we can find I(t) as follow:

Thus, Applying Kirchoff's Law (sum of all voltages is zero) on the circuit in the figure attached below, we get

V_(s)-V_(R)-V_(c)(t) =0

putting values, we get

3.0-I(t)*R-0=0

I(t)*100=3

I(t)=(3)/(100)

Current in the circuit is I(t)=0.03A\ OR\ 30mA

Part.c: Vc(t) and I(t)=? if switch is opened

If switch is opened and capacitor is fully charged then the capacitor will act as a battery and will supply will voltage as it has stored the charge. The switch is open it means the circuit is open.

So current I(t) in the circuit is zero=0A

and voltage Vc(t) exist which can be found as:

Applying Kirchoff's law, we get

V_(s) -V_(c)(t)=0 \nV_(R)\ does\ not\ exist\ because\ current\ in\ the\ circuit\ or\ through\ resistor\ is\ zero

V_(s)=V_(c)(t)

thus voltage on the capacitor is V_(c)(t)=3.0V

Should political leaders adhere to basic moral principles when pursuing the state’s affairs or just look out for the state’s interests?

Answers

Answer:

Political leaders must address these two factors in a balanced and harmonious way.

Explanation:

Being a political leader is a very big responsibility, as it must meet all the principles, concepts, needs and guidelines that the territory they represent presents. In this case, political leaders, within the ethics of the position they represent, are not allowed to choose whether to meet the moral limits of state conduct, or whether to serve the interests of the states, because their obligation is to serve these two factors of equal, balanced and harmonious form as established by the states they represent.
