Question

Assertion : Wires used in heater elements should have high resistivity and a high melting point.
Reason : Heater wires are made of an alloy having resistivity higher than that of its constituent
metals.

Answer 1

Answer:

BOTH A AND R ARE CORRECT AND R IS THE CORRECT EXPLANATION OF A.

brainliest pl☺

Answer 2

Explanation:

BOTH ASSERTION AND REASONING ARE CORRECT.

High resistance assure that more heat is produced and water heats up quickly.....as heat generated is directly proportional to resistance.

Also high melting point of alloy assure that the wire do not break down during heating process.

THANK YOU

hope it helps you
