Consider the segment of a circuit shown in the figure.
A point labeled a is connected to the left
end of inductor labeled L. The right end of the
inductor is connected to the left end of a resistor
labeled R. The right end of the resistor is connected
to a point labeled b.
At a certain time, the current in the segment
is 1.60 A and is increasing at a rate
of 0.503 A/s. The measured voltage at this time
is
ΔVab = 9.30 V.
At another time, when the current is
again 1.60 A but
now decreasing at the rate
of 0.503 A/s, the measured voltage is
ΔVab = 5.52 V.
What are the values of L (in H)
and R (in ohms)?
L= HR= Ω
(b)
What If? The current and rate of change
for the circuit segment above (with the same resistance and
inductance) are again measured at two different times. The current,
once again, at both times is 1.60 A. Again the rate
of change of current is increasing at the first time and decreasing
at the second, but the magnitude of the rate of change at both
times is 1.006 A/s, two times the value from part
(a). What is the difference in measured voltage between the instant
when the current is increasing and the instant when it is
decreasing? (Give your answer in V.)
