Good question. I have one of these chargers and my understanding is that it just needs to be plugged in. I'm not quite sure if the power needs to be on or off when it's charging but mine seem to work for multiple charges even when I thought it wasnt charged. I'm going to call the manufactuer and see what they have to say as well. I hope this some what helps.
That was my first answer and then I located the manufactuer
1. You plug an extension cord into it
2. plug it into a wall outlet
3. power it on
4. select the amps 2/4/6 by pressing the amp button once, twice or three times.
Do NT let the product charge for more than 3-4 hours
if your intrested in the manual just send me an e-mail to onyx@ce-x.com
Good Luck.
vector
Charge is not a vector.
scalar
From an electric field vector at one point, you can determine the direction of the electrostatic force on a test charge of known sign at that point. You can also determine the magnitude of the electrostatic force exerted per unit charge on a test charge at that point.
Current Density describe how charge flow at certain point since current density = I/A and the vector direction tells you about the direction of flow at that point.
specific charge is because a physical quantity can be complete only when by giving magnitude only. Here the physical quantity is complete by its magnitude.
Electric potential is a scalar quantity since work done and charge are scalars
A vector exception is a charge that had to be manually inputed into an account. Whether it be an old check, posting charges over a hard hold on an account, or even check that had to be clear by fraud operations. A quick call to your bank should illuminate you on why a charge had to be manually entered into the account.
Both. The electric field is a Quaternion field, a scalar e and a vector E, E = [e,E]Maxwell's Equation. 0=XE= [d/dr, Del][e,E] = [de/dr -Del.E, dE/dr + Del e] = [db/dt - Del.E, dB/dt + Del e]
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
The Force on a point charge from another point charge is along the Line connecting between the two charges. The direction will be towards the point charge if the two charges are different and away if they are same.Now if you collection of Charges then it is vector sum of force due to each charge.
NULL VECTOR::::null vector is avector of zero magnitude and arbitrary direction the sum of a vector and its negative vector is a null vector...
