Question

wires A and B of the same material have their lengths in the ratio 1 ratio 2 and their radii in the ratio 2 ratio 1 talk to life are connected in parallel across a battery the ratio of the heat produced in a to the heat produced in B for the same time​

Answer 1

Explanation:

HEY MATE

HERE IS YOUR ANSWER

AS WIRES ARE CONNECTED IN PARALLEL

THEN VOLTAGE REMAIN SAME

AS HEAT=V²t/R

AND AS WE KNOW

R=RHO×L/A

WHERE RHO SAME FOR MATERIAL

AND

THEN

HEAT IS INVERSELY PROPORTIONAL TO R

H= 1/R

H=A/RHO L

H¹/H² = A¹/A² × L²/L¹

H¹/H²=r1²/r2² ×L2/L1

H¹/H2 = 4/1 × 2/1

H1 /H2 = 8/1

SO THE RATIO OF HEAT IS 8:1
