What are the examples of change of energy from electrical to chemical?
One example is in the process of photosynthesis, where plants convert electrical energy from sunlight into chemical energy stored in glucose molecules. Another example is in the operation of batteries, where electrical energy is converted into chemical energy during charging and then reversed during discharging to power devices.
Is it possible to interconvert chemical and electrical energy?
Yes, it is possible to interconvert chemical and electrical energy. For example, in a battery, chemical energy is converted into electrical energy during discharging, and electrical energy can be used to generate chemical reactions during charging. This interconversion is what allows batteries to store and release energy.
What changes electrical energy into chemical energy?
Electrical energy can be changed into chemical energy through a process called electrochemical reactions. This conversion occurs in batteries or fuel cells where electrons flow through a circuit, creating a chemical reaction that stores or releases energy.
Can chemical energy be converted to electrical energy?
Yes, like in charging up a battery.
What is cathode made from?
Cathodes are typically made from materials like nickel, cobalt, manganese, and aluminum in lithium-ion batteries. These materials help to store and release energy efficiently during the charging and discharging processes.
What energy transformation in an electrochemical cell cell when charging and discharging?
When charging, electrical energy from an external source is converted into chemical energy, which is stored in the cell. During discharging, the stored chemical energy is converted back into electrical energy that can be used to power devices.
What is the biggest difference between the processes of charging and discharging when you compare them?
The biggest difference between charging and discharging is that charging involves adding energy to a battery or device, while discharging involves releasing energy from a battery or device.
What is active material in the positive plates of a charged add storage?
The active material in the positive plates of a lead-acid storage battery is lead dioxide (PbO2). Lead dioxide is responsible for the electrochemical reactions that occur during charging and discharging, allowing the battery to store and release electrical energy.
What is a battery's waste energy?
A battery's waste energy is the energy that is lost as heat during the charging and discharging process. This energy is not converted into useful electrical energy and represents inefficiencies in the battery system.
Why capacitors are not connected in series in power line?
capacitor's characteristic is charging and discharging. discharged energy will be dropped by load . so it is connected in parallel
What are the examples of change of energy from electrical to chemical?

Another example is in the operation of batteries, where electrical energy is converted into chemical energy during charging and then reversed during discharging to power devices.
How do you make a rechargeable battery have electrical and thermal energy?
To make a rechargeable battery have electrical energy, it needs to go through a charging process where it stores electrical energy. Thermal energy is a byproduct of the charging and discharging processes due to internal resistance and inefficiencies in the battery, so the battery naturally generates some thermal energy when in use.
Why can't a rechargeable battery give as much energy as was put into it?
The reason is that the charging and discharging processes are not 100% efficient. In other words, when charging (and discharging) a battery, some of the energy is wasted doing other thing than actually charging the battery. For instance, you'll notice that batteries get warm when being charged. That heat is an indication that some energy is being lost to heat during the process. It is impossible to make a real working battery that can be charged and discharged with 100% efficiency. In fact, most batteries are pretty inefficient! That is why using batteries on a large scale (for instance to power an entire building or city) isn't an efficient use of energy. To much energy is lost in the charging and discharging process. However, batteries are the way that most electrical energy is stored and is the only fully self-contained portable way (other ways are compressed air and pumping water uphill).
Which acid is used in lead storage batteries?
The acid used in lead storage batteries is sulfuric acid (H₂SO₄). It serves as the electrolyte in the battery, facilitating the electrochemical reactions between the lead dioxide (PbO₂) and sponge lead (Pb) electrodes during charging and discharging processes. This reaction generates electrical energy, making sulfuric acid essential for the battery's operation.
What is the efficiency of batterys?
The efficiency of batteries is typically around 80-90%. This means that when charging a battery, 80-90% of the input energy is stored as chemical energy, and when discharging a battery, 80-90% of the stored energy is converted back to usable electrical energy.
How inductor charge and discharge?
An inductor stores energy in a magnetic field when current flows through it, which is referred to as charging. When the current decreases or is interrupted, the inductor releases that stored energy back into the circuit by inducing a voltage in the opposite direction, leading to discharging. This energy transfer can cause a brief surge in current, which is why protective components like diodes are often used in circuits involving inductors to prevent damage. The behavior of an inductor during charging and discharging is governed by the principles of electromagnetic induction.
Is it possible to interconvert chemical and electrical energy?
Yes, it is possible to interconvert chemical and electrical energy. For example, in a battery, chemical energy is converted into electrical energy during discharging, and electrical energy can be used to generate chemical reactions during charging. This interconversion is what allows batteries to store and release energy.
