Capacitors used in electronic circuits need not have a minimum voltage rating of 25 volts. Electronic circuits powered by batteries at 12 volts and below should work fine with capacitors rated at 15 volts.

What is difference between electric and electronic?
Sometimes the terms are used interchangeably. But roughly speaking, electric circuits include voltage sources such as batteries, as well as "passive" components, such as resistors, inductors, and capacitors - whereas electronic circuits include those, but also additional components with a non-linear characteristic (i.e., a more complicated behavior), such as rectifying diodes and transistors.
What is the function of electrolytic cell?
Electrolytic capacitors are used for power filter, decoupling, signal coupling and time constant setting, DC blocking, etc. Polarized electrolytic capacitors usually play a role in power supply circuits or intermediate frequency and low frequency circuits for power supply filtering, decoupling, signal coupling, time constant setting, and DC blocking. Generally electrolytic capacitors cannot be used in AC power circuits. When used as filter capacitors in DC power circuits, its anode (positive) should be connected to the positive terminal of the power supply voltage, and the cathode (negative) should be connected to the negative terminal of the power supply voltage. Otherwise it will damage the capacitor. We're JYH HSU(JEC) Electronics Ltd (or Dongguan Zhixu Electronic Co., Ltd.), an electronic components manufacturer.

Why is the voltage of the NiMh decrease on battery cell?
All cells drop in voltage as they lose their charge. Often old cells do not attain full voltage even at their maximum charge. It's just the way the chemistry works. Electronic systems that require constant voltage have regulation circuits that step the voltage up to the necessary level and keep it constant, even though the battery voltage may be dropping.
Can you double the volts by connecting two capacitors?
Two capacitors can be connected in series to double the voltage rating, but they must be identical capacitors and they should each have a resistor in parallel to equalise the voltages, the resistors chosen to pass about 1 mA. With two capacitors in series the overall capacitance is half the capacitance of either capacitor. The combination stores equal charge at double the voltage and the stored energy is doubled.
Why capacitor is said to be a reactive component?
In electrical or electronic circuits, impedance can be said to have capacitive or inductive components. Capacitors cause capacitive impedance, and coils (chokes, transformers, loudspeakers, etc.) cause inductive impedance. A capacitor is said to be a reactive component in an AC circuit because it holds charge, then releases it, causing a phase shift in the output current. This phase shift in current equates to a phase shift between current and voltage. Reactive power is defined as a phase shift between current and voltage.
How only capacitors can give smooth ac voltage waveform when used in ac circuits?
Capacitors resist a change in voltage, inversely proportional to their capacitance. As a result, transients in the AC line tend to be filtered out.
What is the difference between electricity and electronics?
Electricity is a form of energy that results from the existence of charged particles such as electrons and protons either as an accumulation or statically.The relationship between voltage, current and resistance.Electronics uses the principles of electricity through electronic components for example resistors, transistors, coils, integrated circuits, capacitors etc.Electricity is the relationship between voltage, current, and resistance. Electronics utilizes the principles of electricity through electronic components, such as coils, capacitors, resistors, diodes, transistors, integrated circuits, etc.
Do electrical devices that are plugged in but not turned on still consume electricity?
Electronic circuits often contain filter circuits that are ahead of the power switch. These Filters contain capacitors between phase and neutral, so called X-Capacitors and between phase and ground respectively neutral and ground, so called Y-Capacitors. These capacitors in conjunction with the the applied alternating voltage are causing a current to flow. Often built in over-voltage protection circuits have got an capacitance (even if it is low) and are causing a minor current to flow. In the stricht sense even the power cord has got a small capacitance and causes a minor current to flow.
Why electronic circuits work at 24volts?
A circuit is designed to work at a specific voltage and that voltage only.
Is there a minimum derated voltage that tantalum capacitors should be operated at?
Yes, 1/3
Why you are using rectifiers in electronic circuits?

What use of c in circuits?
C = capacitors. Capcitors can be used to store voltages so that they become voltage sources, or they can be used in mixed A/D circuits as timers, attenuators, filters, etc.
What is the principle of operation of a ballast?
Older ballasts with an iron core are basically an autotransformer. They transform voltage to a higher voltage with a single winding. Electronic transformers increase voltage with capacitors and diodes.
What is the labeling nomenclature for capacitors and how is it used to identify and select capacitors?
Capacitors are marked with the capacitance and the maximum working voltage. The action of a capacitor is store charge short-term and a capacitor is commonly used as a reservoir of charge in a rectifier circuit to smooth the dc output voltage. Other uses in electronic circuits are as a dc-blocker which passes an ac signal while not passing the dc bias, or as a decoupling capacitor in dc circuits to remove any ac signals present while preserving the dc voltage, or in timing circuits because the time-constant of a resistor and a capacitor connected together is CR, or in filters and tuned circuits. Sometimes a variable capacitor is used, connected to a control knob for tuning a radio. In each of the above applications there are accurate methods to decide exactly how much capacitance is required.
Where are capacitors used?
Capacitors are used in many different ways.Here are a few instances where they are used:in amplifier circuits to isolate small signal circuitry from amplifier circuits' DC biasin power supplies to minimize AC ripple on the DC waveformin timer circuits to create specific patterns and frequencieswith integrated circuits to prevent ripple from the power supply from reaching the ICin analog computation machines for creating integrators and differentiatorsin high voltage AC systems to "add VARs" to the system.
