How many 100 ohm resistors (in parallel) are required to carry 10A on a 200V line?​

Answer»

tion:Given:- V=200v I=10A R¹ = 100 ohm N=? So, R(s) = V/I => R(s) = 200/10 : R(s) = 20 ohm ----------1 now, R(s)= R¹/n---------2From 1 and 2 we get ,20 ohm= R¹/nso, n=R¹/20 n =100/20 n = 5 hence 5 resistors are NEEDED.. hope it helps plzzzz mark as BRAINLIST
