Question

Define 1) Resistivity 2) Electric circuit

Answer 1

Answer:

1) a measure of the resisting power of a specified to the flow of an electric current.

2) an electric current is a rate of flow of electric charge past a point or Reason

Answer 2

Resistivity-The resistivity of a substance is numerically equal to the resistor of a rod of that substance which is, 1 metre long and 1square metre in cross section.

Electric Circuit-A close, continuous and conducting path consisting of wire and other resistances(like electric bulb,ammeter,cell,etc.) and a switch,between two terminals of a cell or a battery along which an electric current flows,is called an electric circuit.
