_________ and ________ can be considered to be an electrical analogy for water flow and water pressure in a pipe respectively. 

Select the wrong statement about electric field.

For different positions of test charge, we get same values for electric field.

The electric field $E$ due to $Q$, on the test charge $q$, is independent of $q$.

Define electic field.

Mention the factor that maintains the flow of charge through a conductor.
