The circuit you’re making needs a 1.5?? capacitor but you only
have three 1?? capacitors. Draw how you make an equivalent
capacitor from the 1?? capacitors.
If the capacitor in an RC circuit is replaced by two identical
capacitors connected in series, then find the CORRECT
statement.
Select one:
a. The time constant will be tripled
b. The time constant will decrease by a factor of 2
c. The time constant will be unchanged
d. The time constant will decrease by a factor of 4
e. The time constant will be doubled
You are working with a team designing capacitors for specialized
purposes. One client needs a capacitor shaped like a sphere that
can store the most energy for its size. You are to begin the design
process by performing calculations for a simple spherical capacitor
consisting of two thin concentric spherical shells separated by a
dielectric. You decide to calculate the maximum energy that can be
stored in terms of the radius of the outer shell and the maximum
electric field...
Four capacitors are arranged in the circuit shown in the figure.
The capacitors have the values C1 = 39.5 μF, C2 = 13.5 μF, C3 =
45.5 μF, C4 = 85.5 μF, and the power supply is set at voltage V =
16.5 V.What is the equivalent capacitance of the circuit?What is the charge on capacitor C3?What is the potential difference across capacitor C4?What is the potential energy stored in capacitor C2?
Three capacitors are arranged as shown as a portion of a
complete circuit. ?2 and ?3 are wired in parallel, and then the
system of (?2 + ?3) is wired in series to capacitor ?1. The
capacitances of each capacitor are ?1 = 5.1 ??, ?2 = 4.8 ??, and
C3= 6.2 ??. There is an unknown potential difference between points
a and b. a. What is the equivalent capacitance of the system? b. If
the charge on ?2 is...
Three capacitors of 10muF, 25muF, and 50 muF are connected in
series. Each capacitor is rated for 24V operation. is it safe to
apply a total of 24V x 3=72 across their combination? If not safe,
what is the maximum voltage that can be supplied across their
combination so that the voltage drops across any of the three
capacitors will not exceed their rated voltage of 24V?
You’re doing an experiment in a physics lab using ice and water.
Do you have 1.5 kg water with temperature 28°C. You added 0.6 kg
ice with initial temperature -22°C. Assuming you have an isolated
system,
i) write down the thermal equilibrium equations with amount of
heat loss and gain in the system
ii) do all the icemelt justify your answer with calculations
iii) what is the final temperature of the water in the container
and why?
iv) if some...
Implement a circuit for following scenario using NOR gate only,

In a certain chemical – processing plant, a liquid chemical is used
in a manufacturing process. The chemical is
stored in three different tanks. A level sensor in each tank
produces a HIGH voltage when the level of the chemical in
the tank drops below a specified point. Design a circuit that
monitors the chemical level and indicates when the
level in any two of the...
