But in parallel combination potential remain constant?

Design and draw pie type high pass filter having cut of frequency of 2kHz and load resistance of 500Ω

Two large parallel conducting plates carrying equal and opposite charges on their
surfaces facing each other are placed at a distance of 0.75 m. An electron placed at
some point between the plates experiences an electrostatic force of 4.8 × 10-16 N.
Calculate the magnitude of the electric field at the position of the electron between
the plates. Also determine the potential difference between the plates.

On the basis of their biasing, with the help of appropriate diagrams, justify the uses
of Class A, AB and C amplifiers for various applications.

A resistance R and inductance L=0.01 H and a capacitance are connected in series when a voltage V=400Cos (300t-10) v is applied to the series combination, the current flowing I=10 √2cos (300t-55°)A. Find P and C.

An R, L and C series circuit consists of a resistor of 100 ohms and an inductance of 100mh and a capacitance of 10 micro micro farad. If the voltage of 100v is applied across the combination. Find the resonance Q factor of the circuit.

I want insert a picture of circuit. How??

Design a three-channel inverting adder to satisfy the following relation:
V.= (-10V1 + 0.5( dV2/dt) + 2V3 )

State, with reasons, whether the following statements are True or False.
i) Inductor is a unilateral device.

ii) Beheviour of the quality factor Q of a series LCR circuit is opposite to that of
parallel LCR circuit.

iii) A trivalent element is added to silicon to obtain an n-type semiconductor.

iv) Highest voltage gain is obtained in common collector configuration of an
amplifier.

v) For generating high frequency signals RC oscillators are preferred over LC oscillators.

vi) Op-amp comparator compares the input signal only with zero-voltage level.

vii) Non-inverting amplifier uses op-amp in positive feedback mode.

viii) The highest hexadecimal number counted with 8-bits is 7E.

ix) All the logic gates can be realized using combination of only AND gates.

x) Siemens wattmeter can be used to measure dc power.

Please very very urgent

A 2 microfarad capactior is charged to 50 V and then connected in parallel (positive plate to positive plate) with a 4 microfarad capacitor charged to 100 V.
a. What are the final charges on the capactiors?
b. What is the potential difference across each?
c. Repeat a and b if the positive plate of one capacitor is connected to the negative plate of the other.
