Does electric field depend on diameter?
The maximum electric field strength at the surface of conductors depends on the maximum operating voltage, diameter of the subconductor, bundle configuration of phase conductors, and phase-to-phase spacing.
Does current density depend on area?
The current density in a conducting wire depends on the current through the conducting wire and the cross-sectional area of the wire. … The current density is proportional to the current and inversely proportional to the area.
Does current depends on area of cross section?
In a series combination of resistances same current flows through all the resistors, no matter what there cross-sectional areas are, what their lengths are, what is the value of resistances and even the material of the wires maybe different, current flowing through them will be same always.
What are the factors affecting the electric field strength?
The new formula for electric field strength (shown inside the box) expresses the field strength in terms of the two variables that affect it. The electric field strength is dependent upon the quantity of charge on the source charge (Q) and the distance of separation (d) from the source charge.
How does current density in a conductor vary with area?
Current-density is a vector quantity. If potential difference V is applied across a conductor of length ‘l’ and area of cross-section ‘A’ having number of free electrons per unit volume n. … (b) when temperature increases, relaxation time (τ) decreases and current density decreases.
How does diameter affect current density?
The Effect of Amperage
As the amperage flows through the smaller diameter wire, the density (or concentration) of current is greater than that same current flowing through a larger diameter wire. … At that point, it is time to increase the wire diameter. This will lower the current density and stabilize the arc.
What is the relationship between electric field and the distance of separation between the plates of a parallel plate capacitor?
In a simple parallel-plate capacitor, a voltage applied between two conductive plates creates a uniform electric field between those plates. The electric field strength in a capacitor is directly proportional to the voltage applied and inversely proportional to the distance between the plates.
Does the electric field between the plates increase/decrease or remain the same as the plates are moved closer together?
As you move the plates closer at the same applied voltage, the E field between them (Volts per meter) increases (Volts is the same, meters gets smaller). This stronger E field can hold more charges on the plates.
