When a potential difference of 4V is applied across resistance 10 J if energy is converted find charge that flows?
The question may be defective. It seems to describe a one-time event, whereas
the situation is virtually always a steady-state condition. I'll try to answer both
concepts:
-- Answer to what you actually asked:
1 volt of EMF corresponds to 1 joule per coulomb of charge that climbs or falls through it.
Voltage = (charge) x (energy)
Charge = voltage/energy = 4 volts/10 joules = 0.4 coulomb of charge
-- Answer to what I think you intended to ask:
Rate of energy dissipation, called "power" = (voltage) x (rate of flow of charge, called "current")
Current = power/voltage
10 joules per second/4 volts = 10 "watts"/4 volts = 2.5 coulombs per second = 2.5 "Amperes"

When a steady potential difference is applied across the ends of a conducting wire?
Current flows through the wire due to the movement of free electrons within the material, in response to the electric field established by the potential difference. The current is directly proportional to the applied potential difference, as described by Ohm's Law, provided the material's resistance remains constant.
What is the net force when encounters 15 N air resistance?
The net force would be the difference between the applied force and the air resistance. If the applied force is greater than the air resistance, then the net force would be in the direction of the applied force. If the air resistance is greater than the applied force, then the net force would be in the opposite direction.
How does height affect acceleration?
Height does not directly affect acceleration. Acceleration is determined by the force applied to an object, its mass, and any friction or air resistance. However, height can influence potential energy, which can be converted into kinetic energy and affect the speed of an object as it moves downhill.
A 1.5m wire carries a 3 A current when a potential difference of 75 V is applied. What is the resistance of the wire?
The resistance of the wire can be calculated using Ohm's Law, which states that resistance (R) is equal to voltage (V) divided by current (I). So, R = V / I. Plugging in the values, R = 75 V / 3 A = 25 ohms. Therefore, the resistance of the wire is 25 ohms.
How much is the potential difference between the terminals of a connection wire?
The potential difference between the terminals of a connection wire is determined by the voltage difference applied across the wire. This voltage difference creates an electric field within the wire that causes charge carriers to move and establish a potential difference between the terminals.
Does increasing potential difference increase resistance?
Resistance is due to a property specific resistance of material. In no way resistance depends on the voltage applied. This is the case of ordinary conductor. But in case of semi conductor or insulator there may be chances to get a variation of conductance and hence resistance due to potential applied.

What is the ohm?
The Ohm is a unit of measure of resistance to the flow of electricity. The ohm is defined as a resistance between two points of a conductor when a constant potential difference of 1 volt, applied to these points, produces in the conductor a current of 1 ampere.
What is the net force when encounters 15 N air resistance?
The net force would be the difference between the applied force and the air resistance. If the applied force is greater than the air resistance, then the net force would be in the direction of the applied force. If the air resistance is greater than the applied force, then the net force would be in the opposite direction.
What is difference between resistance and reactance while both are measured in ohms?
Resistance is constant no matter the frequency applied. Reactance varies depending on the frequency of the power applied to it.
What is the difference between resistance and resistor?
Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it. A resistor is a electrical componet with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc.. depending on how much current you want to pass through a circuit, you would design the circuit with the required resistors

burn or burst

How do you create an ohm?
The ohm is defined as a resistance between 2 points of a conductor when a constant potential difference of 1 volt, applied to these points, produces in the conductor a current of 1 ampere, the conductor not being the seat of any electromotive force.
What must be applied for electrons to move in the same direction?
electromotive force...
