The charge across the capacitor in two different RC circuits 1 and 2 a...
The charge on capacitor at any time t is q=qmax​(1−e−t/CR)
As the qmax​ of both curves is the same so both capacitors will be charged to the same charge.
As (2) curves take more time for maximum charging so the time constant of curve (2) is greater than (1). i.e, τ2​>τ1​⇒C2​R2​>C1​R1​
As qmax​ is same for both curve so C1​E1​=C2​E2​
Since C1​ and C2​ are different so emf of both cells may be different.
now E1​=(C2​/C1​)E2​>(R1​/R2​)E2​
If R1​>R2​ , then E1​>E2​.

Point A is evident from the graph itself.
For point C, E=IR. I is different because time for charging is different for both of them.

Read the following text and answer the following questions on the basis of the same:Supercapacitor: Super capacitor is a high capacity capacitor with a capacitance value much higher than normal capacitors but with lower voltage limits. Such capacitors bridges the gap between electrolytic capacitors and rechargeable batteries. In automobile, bus, train, crane, elevator such capacitors are used for regenerative braking, short term energy storage or burst-mode power delivery.Super capacitors have many advantages over batteries: they are very low weight and generally don't contain harmful chemicals or toxic metal. They can be charged and discharged innumerable number of times without ever wearing out. The disadvantage is that super capacitors aren’t well-suited for long-term energy storage. The discharge rate of super capacitors is significantly higher than lithium-ion batteries; they can lose as much as 10-20% of their charge per day due to self discharge.Capacity of supercapacitor is

Read the following text and answer the following questions on the basis of the same: Power factor correction capacitor Power factor correction is a method to reduce the lagging power factor in inductive loads by fixing a high value capacitor across the phase and neutral line close to the load. When the Voltage and Current are in phase with each other in an AC circuit, the energy from the source is fully converted into another form to drive the load and in this case the power factor is in unity. When the power factor drops, the system becomes less efficient. In inductive loads, current “lags'' the voltage leading to “lagging power factor”. Power factor correction is the method to reduce the lagging power factor in inductive loads by fixing a high value capacitor across the phase and neutral close to the load. These capacitors have leading power factor so that it will neutralize the lagging power factor of the load. Power capacitors are huge non polarized metal film electrolytic type capacitors. Capacitors should be sufficiently rated to the load capacity. It should be connected to the lines, only when the loads are running and drawing currentPower factor corrector capacitors should be connected
