Question 4 of 7

Assertion (A): Alloys are commonly used in electrical heating devices like electric iron and heater.
Reason (R): Resistivity of an alloy is generally higher than that of its constituent metals but the alloys have low melting points then their constituent metals.

Question 5 of 7

Assertion (A): In a simple battery circuit the point of lowest potential is positive terminal of the battery.
Reason (R): The current flows towards the point of the lower potential as it flows in such a circuit from the positive to the negative terminal.

A Both A and R are true, and R is the correct explanation of A. B Both A and R are true, but R is not the correct explanation of A. C A is true, but R is false. D A is false, but R is true.
