How do rechargeable batteries work?
Click the link below A rechargeable battery is also known as an accumulator. It uses one or more electrochemical cells. During the charging process the cathode end which is the positive has negative electrons pushed through it mixing in the small chamber of the battery. The anode has positive electrons come in. The positive and negative electrons are combined and mixed inside and are released from metal to metal contact and are then used as electricity.
What is a positive DC voltage?
A positive DC voltage is an electric potential where excess electrons will flow from negative to positive.AnswerYou appear to be mixing up potential difference (i.e. voltage) with potential. There is no such thing as a 'positive' voltage if you mean 'positive' in the sense of charge! 'Voltage' means 'potential difference', and you cannot have a positive or negative potential difference in this sense. You can only apply positive and negative in this sense to potentials.However, if you mean 'positive' in the sense of direction, then a positive voltage is one that is acting in the opposite direction to a negative voltage within the same circuit. For example, where two batteries have been connected in opposition.
What are the implications of having type a negative blood?
The negative blood comes from the rhesus scale. So type A negative blood means you are rH negative. This poses a potential problem during pregnancy if the mother is rH negative and the father is rH positive. In that case the mother will receive a rhogam shot during pregnancy and right after birth to prevent the potential mixing of blood between mother and child from causing a serious reaction in the mother's body.
How does a battery charger charge a battery?
what kind of batteries do you have?? if the mobile phone's battery, just put in your phone. If it's car battery, just connect the red cable to positive, black cable to negative plates. on rechargeable alkaline type batteries the charger should have a plus and negative sign on it. usually the neg end is the one with the spring. the flat end of the battery is usually negative.
Your husband is negative blood type and you are positive blood type do you have to get some kind of injection to get pregnant?
I'm not too sure whether or not there'll be any difference. I don't think blood type is relevant to reproduction. If you're really not sure or you're worried about it, then consult your GP. No. Blood type has nothing to do with getting pregnant. The only time blood type matters is if the mother is negative and the unborn child is positive (note: the father would also have to be positive), then the mother will have to receive a shot to reduce the risk of miscarriage. No. The only time you would have to get the injection is if you were negative and he was positive. And that's only with your second child because of the mixing Rh factors.
What is the optimal battery electrolyte mixing ratio for maximum efficiency and performance?
The optimal battery electrolyte mixing ratio for maximum efficiency and performance is typically around a 1:1 ratio of acid to water. This balance helps to ensure proper conductivity and chemical reactions within the battery, leading to improved overall performance.
What are the benefits of o negative blood?
If you are a blood donor your blood can be given to anyone. Everyone who is O negative is OO negative, by father, husband and both my sons are all O negative. If you are a rhesus negative woman married to a rhesus positive man you may need to have Anti-D while pregnant and after delivery to prevent your blood becoming sensitised and affecting a Rhesus positive baby More elaborate answer on pregnancy in rhesus negative women: If you are a rhesus negative woman pregnant by a rhesus positive partner you WILL (typically only after the first pregnancy, but, it's suggested with any pregnancy of a Rh- woman) need a RhoGAM (Anti-D) injection in early pregnancy to protect the embryo from being miscarried from an attack by your immune system and again during or immediately after delivery to stop the fetal blood (which most likely will be positive) from mixing with your blood preventing your death. Negative can successfully mix with positive, but, positive will kill a negative.
Why does oil not mix with water?
Oil does not mix with water because oil molecules are nonpolar, meaning they do not have a charge, while water molecules are polar, with a positive and negative end. This difference in polarity causes oil and water to repel each other, preventing them from mixing together.
If sugar dissolves in tea is it positive or negative?
When sugar dissolves in tea, it is considered a physical change because the sugar molecules are dispersing and mixing with the tea molecules, creating a homogeneous solution. Therefore, this dissolution process is positive because it results in a uniform solution, enhancing the taste of the tea.
What exactly is a chemical reaction?
A chemical reaction is what takes place when two or more opposing chemical come together and cause some sort of reaction, either positive or negative. An example would be mixing bleach and ammonia which will trigger a very noxious smell which can lead to serious illness.
If a man is Rhesus negative and wants to procreate with a rhesus positive woman. Is there need for rhogam to avoid miscarriage?
Yes, if a man is Rh negative and the woman is Rh positive, there is a risk of Rh incompatibility that can lead to miscarriage in future pregnancies. It is recommended that the woman receive Rhogam injections to prevent the development of Rh antibodies in case of fetal-maternal blood mixing during childbirth or pregnancy complications.
Why do we get a murky color and not white when mixing the seven colors of the rainbow?
It depends if you are you mixing light, or if you are mixing paint. Enough different colors of light, in the correct proportions, can make white. More than 2 or 3 colors of paint, no matter what the proportions, usually makes something like peanut butter.The difference is the color system used. Light uses the positive system, where if you mix red, green, and blue light, you get white. But, with paints, the negative system applies, and if you mix cyan, yellow, and magenta, you get black.
