Question

Suppose a voltage divider is constructed from two fixed resistors.
If *V*_{IN} = 25 V,
*R*_{1} = 108 Ω, what should the value of
*R*_{2} be so that *V*_{OUT}
is 10 V?

*R*_{2} = ΩThe circuit diagrams display a
device called a voltage divider.

In a voltage divider, if is the source voltage, then voltage across the resistor is given by,

You have two resistors, R1 and R2, and you know that R1 = 10 kΩ.
You set up the voltage divider circuit shown in Fig. 7.9 where the
battery voltage, V0, is 9 V. You measure Vout to be 3 V. What is
the value of R2?

In a two-story voltage amplifier circuit, there is PNP on the
first floor and NPN on the second floor. A total of 10 resistors
and a total of 5 capacitors were used in the circuit, 5 resistors
per floor. Re resistance of PNP transistor is 63.31 Ω and re
resistance of NPN transistor is 15.25 Ω. The input impedance of the
first floor is 212.36 Ω and the input impedance of the second floor
is 9.1 K Ω. There is...

Two resistors, with resistance R1= 5 ohms and R2=25 ohms are
connected in series in a circuit. The current flow generates heat
at a rate of 1280 J/s in R1. What is the voltage drop across
R2?

A power supply of 47 V is connected to two resistors of R1=47000
ohms and R2=31000 ohms back to back (series circuit). What does the
reading say in a voltage meter that has a inner resistance of 89000
ohms that is connected to the first resister (R1)?

Consider the circuit shown in the figure(Figure 1). Suppose the
four resistors in this circuit have the values R1 = 13 Ω , R2 = 7.2
Ω , R3 = 6.9 Ω , and R4 = 11 Ω , and that the emf of the battery is
E = 15 V . You may want to review (Pages 748 - 751) . Find the
current through each resistor using the rules for series and
parallel resistors. Express your answers using...

A circuit is constructed with four resistors, one inductor, one
battery and a switch as shown. The values for the resistors are:
R1 = R2 = 59 Ω, R3 = 89 Ω and
R4 = 80 Ω. The inductance is L = 350 mH and the battery
voltage is V = 12 V. The positive terminal of the battery is
indicated with a + sign.

A device for accurately generating small forces between two
wires can be created by the rectangular circuits shown in the
figure on the worksheet for this problem. In the left circuit, the
battery has an emf of ε1 = 6 V and a resistor with fixed resistance
R1 = 4 ohms. In the right circuit, the battery has emf of ε2 = 7 V
and a variable resistor with resistance R2 ohms. The circuits are L
