There are two ways to look at current.
Conventional current (measured in amps) flows from positive to negative. This model works for the vast majority of electrical engineering purposes.
However, current is created by the movement of electrons. Electrons have a negative charge so electrons moving in one direction will give rise to conventional current in the opposite direction. Therefore, although current flows from positive to negative, electrons flow from negative to positive.

What is the return path in three phase three wire line?
out of three phases present one or two of them are negative and remaining +ve current flows back through negative
Why ac current is more dangerous than dc?
no actually dc current is more dangerous than ac because dc is a direct current and has no current zero condition ,which is very dangerous and do not leave us if we get shock while ac current leave us when we get shock
What is an ideal diode?
A: That is no such a diode but if it exists it will have unlimited reverse voltage capability the forward voltage drop will be zero no matter of current flow and it will remain so regardless of temperature changes
How do you connect the parts of a simple electric circuit together so that the light bulb lights up?
Simply connect the -ve of the bulb to -ve of the battery and +ve of bulb to +ve of battery using an electrically conductive wire, the bulb will light automatically.
What happen when plus ve gate pulse given to reverse baise scr?
You cannot turn an SCR off by reverse biasing the gate. Once it is on (anode to cathode), it stays on until the forward current AND the gate current drops to the required threshold level. That said, you can pulse the anode negatively to turn an SCR off, so long as you don't exceed the reverse bias limits of the device. This is how (photographic) flash devices, for one example, can modulate the duration of the flash.
Can O plus ve mother and O plus ve father can give AB plus ve son?
they did not have A and B group at all so they can only produce a baby with O -ve or +ve
Can O plus ve mother and B plus ve father can give A plus ve son?
Can O plus mother and B plus father can give A plus son?
Does negative plus negative equal negative?
I'm pretty sure that -ve plus -ve equals another -ve. -ve plus +ve equals either one of the two, depending on which # is bigger. Same with +ve plus -ve. +ve plus +ve equals +ve. I have done my research and I found out negative plus negative can be negative or positive depending on the bigger number. But, a lot of people make the mistake of subtracting even though the sign is a plus. Example: -7.29 + -3.8= -11.09 but if it was 7.29 + -3.8 the answer 11.09 would be positive because the bigger number is positive.
What is the difference between AC and DC currents?
The difference between AC and DC currents is in terms of current flow. In the case of AC current, current can flow from one point to another and back again. It is reversible. But in the case of DC current, current can only flow in one single direction or from one point to another and not back again.
What is the return path in three phase three wire line?
out of three phases present one or two of them are negative and remaining +ve current flows back through negative
Can two parents with B plus ve will they can produce B-ve baby?
Can a b+ve male and b+ve female produce b+ ve male
How does electric current in a electric cell passes?
From the Positive terminal (+ve) to the negative terminal (-ve).
If both the parents are plus ve blood group then child can be of -ve blood group?
possibility not
Do ionic compounds conduct an electric current in water?
Yes. the +ve and -ve ions move in the presence of an electric field.
Is there any problem to child if mother is AB plus ve and father is O plus plus ve?
Not a problem concerning Haemolytic disease of the newborn (HDN), the mum would have to be rh negative for that to be a potential issue.
Can o plus ve boy marry o-ve girl?
Yes, the O plus boy can marry an O negative girl though there will be a high risk of miscarriage.
Name an ionic compound in which H like plus ve ion?
No ionic hydride in which H like +ve ion.
