Question

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)?

A circuit consists of a power supply and two resistors R1 and R2
connected in parallel. An ammeter is placed to measure the current
through resistor R1.
The ammeter reads I1 = 9.6 mA, and the values of the resistors
are R1 = 6.0 kOhm and R2 = 820 Ohm.
What is the value of voltage across R2?

d. What is power dissipated on 2.00 ohm resistor?

Given three resistors R1 = 4 ohms, R2 = 6
ohms, R3 = 8 ohms and a 12 volt battery source.
Construct a schematic diagram of the third resistor in parallel to
the series combination of the first and second and resistor. Solve
for total resistance, total current, and the voltage through each
resistor

Given R1 = 10 Ohms, R2 = 14 Ohms, and
R3= 9 ohms, calculate the voltage drop across
R3 if the resistor R1 is in series with a
parallel combination of R2 & R3 and the
whole circuit is connected to a 12 V Battery.

Resistor R1=3.7 Ohm is connected in series to parallel combination
of resistors R2=7.9 Ohm and R3=11.1 Ohm. Find equivalent resistance
of this combination. Give answer in Ohms.
Resistor R1=3.7 Ohm is connected in series to parallel combination
of resistors R2=7.9 Ohm and R3=10.7 Ohm. This combination is
connected to the ideal battery of V=10.6 V. Find current through
the R3. Give answer in A.

If two resistors with resistances R1 and
R2 are connected in parallel, as in the figure
below, then the total resistance R, measured in ohms (Ω),
is given by
1/R= 1/R1+1/R2
If R1 and R2 are
increasing at rates of 0.3 Ω/s and 0.2 Ω/s, respectively, how fast
is R changing when R1 = 80 Ω and
R2 = 110 Ω? (Round your answer to three decimal
places.)

If two resistors with resistances R1 and
R2 are connected in parallel, as in the figure

If R1 and R2 are
increasing at rates of 0.3 Ω/s and 0.2 Ω/s, respectively, how fast
is R changing when R1 = 50 Ω and
R2 = 60 Ω? (Round your answer to three decimal
places.)

When two resistors such as R1 and R2 are connected
series, it draws 450 W with a Total current of 5 A. When the
resistors are connected in parallel, they draw 100 W of power for
the same total current. R1 and R2 values how many ohm s? Thank
