how do i solve for J?

Question

Q=I^2Rt / J ( "Q" equals "i" squared times "R" times " t ". All of that over "J". how do I get "J"? do I just divide I^2Rt to the other side?

Answer 1

The easiest way is to multiply both sides by J. Then you will have



QJ = I^2Rt Now divide by Q and you have it.



It sometimes helps to visualize that left side as "Q/1"; then you'll see the equation as a proportion, and you can attack it by cross multiplying (mathematically you'll get the same result as above). Good luck.

Answer 2

J=i^(2)*Rt/Q

deviding it through i^2Rt

would result in Q/(i^2Rt)=1/J

Answer 3

Q = l^2rt/ j

jq = i^2rt

j = i^2rt/q

Answer 4

CROSS MULTIPLY



QJ = I^2Rt



J = I^2Rt / Q
