How many grams of nickel metal are plated out when a constant current of 15.0 A is passed through aqueous NICl2 for 10.0 minutes?
Christinabarnett43
The charge passing through the cell is 15 x 10 x 60 = 9000 coulombs. No. of electrons = 0.0935 mole e- Since nickel has a charge of +2, one atom of nickel will require 2 e- to plate So, 0.0935 mole e- will give 0.0935/2 = 0.04675 mole e- of Nickel. Then one can calculate the no. of gms of nickel that can be plated out.

The constant flow of electrons through a complete circuit?
That is called electrical current.
What is electrolysis of sodium hydroxide?
It is the process of passing an electric current through aqueous sodium hydroxide so that hydrogen is produced at the cathode and oxygen at the anode.
Does light enters through first aqueous humour or pupil?
after pupil first light enters aqueous humour or pupil
Could Electric current through the human body produce Electrolysis of Intersticial Fluid?
Yes, it can. Human fluids include sodium, potassium and other electrolytes that, by definition, include free ions. Current will flow through these electrolytes and will start the process of breaking down the aqueous electrolytes to their constituent elements.
State ohms law?
Ohm's Law states that the current through the conductor is directly proportional to the potential difference between its ends provided its temperature and other physical conditions remain constant
What is the value of the current of a ten ohm resistor which has a constant current and 1200 C of charge flowing through it in 4 minutes?
5 A Q / t = I so 1200/4*60 = 5 A
What is the constant flow of electrons through a complete circuit?
A current.
What will happen if you pass dc current through a single coil?
If dc current is passed through a single coil, it is going to remain constant.

What is electrolysis of sodium hydroxide?
It is the process of passing an electric current through aqueous sodium hydroxide so that hydrogen is produced at the cathode and oxygen at the anode.
What is a ballast resistor?
A ballast resistor is an electrical resistor whose resistance varies with the current passing through it, thus maintaining a constant current.
78xx regulater as a constant current source?
The 78xx regulater can be used as a constant current source, by connecting the output to the input side of a series resistor, and the "ground" to the other side of the resistor. Do not connect the "ground" to real ground - leave it floating.Since the 78xx maintains a constant voltage differential between output and ground, there would be a constant current through the resistor.
What amount of resistance has the least amount of current flow?
The higher the resistance, the less current will flow through it (while the supply voltage remains constant).
Effect on voltage as current increases through constant resistance?
If the current is held constant, the voltage will decrease.
What is voltage and current?
Current is defined as the rate of flow of charge through a body. ie, I = Q / T Voltage is the amount of Pressure needed to make the charge flow through the body. ie, V = J / Q A; current flow is not related to time if the EMF is constant the current flow will be constant. A1: current is electrons flow caused by the presence of EMF. A2: voltage is the EMF force necessary to make current or electrons to flow.

What is Vector meter?
A vector impedance meter is used to measure impedance and phase angle, this is done by calculating voltage and current through an impedance and then calculating Z and phase angle with that, now there are two modes for operation i.e constant current mode and constant voltage mode.CONSTANT CURRENT MODERead more: What_is_vector_impedance_meter_explain_with_circuit_diagram
