Question

Statement-1: When two conducting wires of different resistivity having same cross section area are joined in series, the electric field in them would be equal when they carry current
Statement-2: When wires are in series they carry equal current

• A. Statement-1 is true and Statement-2 is correct explanation for Statement-1
• B. Statement-1 is true and Statement-2 is NOT the correct explanation for Statement-1
• C. Statement-1 is true, Statement-2 is false
• D. Statement-1 is false, Statement-2 is true

Answer 1

The correct option is D Statement-1 is false, Statement-2 is true

The electric field does not exists inside the current carrying conductor. Hence, statement 1 is false.
When the wires are in series their cross sectional area is same hence current density will be equal i.e.current through the wires is equal. Thus, statement 2 is correct.
