When heat flows through a wire of uniform cross section under steady state, then

Assertion : If a current flows through a wire of non-uniform cross-section, potential difference per unit length of wire is same throughout the length of wire. Reason : Current through the wire is same at all cross-sections.

Assertion : If a current flows through a wire of non-uniform cross-section, potential difference per unit length of wire is same throughout the length of wire. Reason : Current through the wire is same at all cross-sections.

Current is flowing through a wire of non-uniform cross section. Cross section of wire at A is les than the cross section of wire at B. Then match the following

Current is flowing through a wire of non-uniform cross section. Cross section of wire at A is les than the cross section of wire at B. Then match the following

(A): If a current flows through a wire of non uniform cross-section,potential difference per unit length of wire in direction of current is same at different points (R): ohms law V = iR is not valid for a wire of non-uniform cross-section

Assertion : When an ideal fluid flows through a pipe of non-uniform cross-section, then pressure is more at that section where area is more if the pipe is horizontal. Reason : According to Bernoulli's theorem speed at broader cross-section will be less.
