heat produced in the wire carrying electric current depends upon current, resistance and time. derive the dimensional formula.
Answers
Explanation:
If the answer is heat = k (I)2 * R * t -5............hre's the solution:
dimensional formula of heat(unit = joule) = [ML2T-2]
let the dependence of heat on the given 3 quantities be as follows:
[ML2T-2] = Ax * Ry * tz
where A = ampere = current, R = resistence , t = time an x, y, z their powers respectively.
equating:
[A0ML2T-2] = Ax *[ML2A-2T3]y * [T]z
= [ Ax-2y * My * L2y * T3y+z]
equating powers of same quantities on both sides:
for 'A' , .........0 = x-2y
.....................x=2y
for M,........y=1
.................x = 2
for T........3y+z = -2
................z = -2-3
................z = -5
therefore,,,
H = k (I)2 * R * t -5
