When the capacitors are connected in series Charge and current is same on all the capacitors. For series capacitors same quantity of electrons will flow through each capacitor because the charge on each plate is coming from the adjacent plate. So, coulomb charge is same. As current is nothing but flow of electrons, current is also same.

6 FAQs about [The first-level error of the capacitor is]
What is the failure mode of a capacitor?
Electromigration is one of failure mechanisms of semiconductor, but the failure mode can appear as a short, open, or characteristic degradation. Capacitors have several failure modes, the degree of which depends on the type of capacitor (Table 1).
What are the different types of capacitor failure?
Capacitor failures can be described by two basic failure categories: catastrophic failures and degraded failures. Catastrophic failure is the complete loss of function of the capacitor in a circuit. Catastrophic failure, such as open or short circuit, is the complete loss of function of the capacitor.
What is a catastrophic failure of a capacitor?
Catastrophic failure is the complete loss of function of the capacitor in a circuit. Catastrophic failure, such as open or short circuit, is the complete loss of function of the capacitor. This failure can cause the enclosure to explode, smoke, ignite, harm other electrical components, or leak liquid or gas from inside the capacitor.
What causes a capacitor to fail?
In addition to these failures, capacitors may fail due to capacitance drift, instability with temperature, high dissipation factor or low insulation resistance. Failures can be the result of electrical, mechanical, or environmental overstress, "wear-out" due to dielectric degradation during operation, or manufacturing defects.
Is it possible to reduce capacitor failures to zero?
However, it is difficult to reduce capacitor failures to zero with the current level of technology. Therefore, this report explains troubleshooting (diagnosis of failures and appropriate measures) to ensure proper and safe use of capacitors.
What causes a hermetically sealed capacitor to fail?
Fatigue in the leads or mounting brackets can also cause a catastrophic failure. The altitude at which hermetically sealed capacitors are to be operated will control the voltage rating of the capacitor. As the barometric pressure decreases so does the terminal "arc-over" susceptibility increase.
