Why thermocouple voltmeter is connected across shunt resistance and electronic voltmeter across capacitor?
There is no such a thing as a thermocouple volt meter. A analogue or digital millivolt meter or volt meter is connected across a shunt or parallel with the shunt to measure the current through the resistor. Say the resistor value = 1 Ohm, then by using the Ohm law formula to calculate the current, say the voltage (voltage drop), read on the volt meter is 1.5 Volt that is R*V = A that is, 1Ω*1.5V = 1.5 Amp.
Any type of DC volt meter, analogue or digital can be used to measure the voltage across a capacitor if the value of the capacitor is large enough that reading will be true RMS. as long as the supply current (EMF Power) are larger than the load current.

What is effect of charged and uncharged capacitor at the resistance of it?
The effect of a charged capacitor on the resistance in a circuit is that it can lead to a temporary increase in current due to the initial discharge when connected to a resistor, while an uncharged capacitor behaves as an open circuit at the moment of connection. Over time, as the charged capacitor discharges, the current decreases exponentially until it reaches zero, effectively behaving like a resistor with a time-dependent resistance. In contrast, an uncharged capacitor will not allow current to flow until it starts charging, resulting in a different initial resistance characteristic. Overall, the capacitor's state (charged or uncharged) influences how it interacts with the resistance in the circuit.
Which Capacitor should be connected in one direction?
The electrolytic capacitor should be connected in only one direction.
Describe the response of a capacitor when connected to and then disconnected from a battery?
A capacitor that is suddenly connected to a battery will charge to the battery voltage. The time to do this is dependent on the current capacity of the battery and wiring, and the capacitance of the capacitor. This represents an instantaneous short circuit, which lasts for a (usually) very short time - but damage could be done if there was no resistance. A charged capacitor that is suddenly disconnected from a battery will hold that voltage. The length of time it will hold is dependent on how much leakage current there is.
Why potential difference is same for each capacitive connected in parallel combination?
Because it is simple phenomenon of electricity everything(resistance,capacitor,inductor) connected in parallel holds the same voltage across the each parallel element.
What would happen to the current flow in a dc circuit when the capacitor is fully charged?
A capacitor charge as a time constant of R resistance C capacitance in ufd and it is defined as 63% for one time constant for the constant voltage source. Electronic engineers assume that a capacitor is fully charged by a 5 times constant. however mathematically speaking it will never be fully charged for obvious reasons. Therefore the answer is current will never stop/
Why one of the leads of resistor connected in electronic circuit is opened while measuring its resistance?
You open one of the leads of resistor connected in electronic circuit while measuring its resistance in order to not introduce error cause by other components in the circuit.

When a capacitor is connected to a circuit, what happens to the current flow through the capacitor?
When a capacitor is connected to a circuit, the current flow through the capacitor initially increases and then decreases as the capacitor charges up.
How capacitor is connected in a table fan?
The Capacitor with running winding is connected in parallel with main winding.
Which Capacitor should be connected in one direction?
The electrolytic capacitor should be connected in only one direction.
How does a capacitor ladder function in electronic circuits?
A capacitor ladder in electronic circuits functions by storing and releasing electrical energy in a controlled manner. It consists of multiple capacitors connected in series and parallel to filter and regulate the flow of current in the circuit. This helps in smoothing out voltage fluctuations and improving the overall performance of the circuit.

What type of electrolytic capacitor will be permanently damaged if connected to the incorrect polarity?
A polarized capacitor will be permanently damaged if connected to the incorrect polarity.
What is electronic discharge?
when a capacitor or any chargeable device connected across a load which may be resistive or inductive than the capacitive device discharges and this discharging of this device is called electronic discharge . it is used in CCD (charged coupled devices).
What is the significance of output resistance in electronic circuits?
The output resistance in electronic circuits is important because it affects how well the circuit can deliver power to connected devices. A lower output resistance allows for better power transfer and efficiency, while a higher output resistance can lead to signal distortion and reduced performance. It is crucial for ensuring optimal performance and stability in electronic systems.
Why potential difference is same for each capacitive connected in parallel combination?
Because it is simple phenomenon of electricity everything(resistance,capacitor,inductor) connected in parallel holds the same voltage across the each parallel element.
What is the output when a fully charged capacitor connected parallel to the inductor?
When an inductor is suddenly connected in parallel with a charged capacitor, the current through the inductor and the voltage between its ends will oscillate at the frequency of F = 1 / 2 pi sqrt(L x C) . With real-world components, having resistance and connected through wire that has resistance, the amplitude of the oscillation will steadily decrease as energy is lost in the circuit, and the oscillation will eventually become too small to measure, and disappear.
