What is the definition of electric current density ?

Description : What is the definition of electric current density ?

Last Answer : Flow density is the flow of electricity flowing through the area of a single cross section per conductor. If the cross-sectional area of a conductor is A and the current flowing through it is I then the current density will be J , J = I / A but I = nAve so J = nAve / A = nve

Write definition of ‘‘Branch’’ and ‘‘Node’’ related to electric circuit.

Description : Write definition of ‘‘Branch’’ and ‘‘Node’’ related to electric circuit.

Last Answer : i) Branch: A part of an electric network which lies between two junctions or nodes is known as branch.  ii) Node: A point or junction where two or more elements of the network are connected together is called as node. 

As we say definition of current is flow of charges then why we give the direction of current from +ve to -ve????

Last Answer : Current flow is like water, water flows from higher level to lower level. Same thing with current, current flows from higher voltage to lower voltage level. The flow of current is in opposite direction of the electron, electron flow from -ve to +ve and current flow from +ve to -ve.
