we know that Q=It and V = W/Q so V=W/It. this implies that Voltage is inversely proportional to current. why then is according to ohm's law is it directly proportional to it?

actually the error in your statement is that the symbol of equal to is not a proportion sovika not say that voltage is inversely proportional to current if there is no proportional sign and if there is an proportional sign then there would be shortly a great change in the equation

but we consider so in other calculation s
yes , if it really meant that V = W ÷ Q.I then change in I will change The value of V in inverse proportion .
Yours answer feels incorrect though . Plz check mine and tell if that feels correct to you
actually you are missing the meaning of proportional symbol

Hello mate ,
Because in V = W ÷ Q .
We always take Q = 1 ( Unit or test charge )
So Q can't put an effect here. Remember We made a assumption that this test charge can't affect .
So It will always be equal to 1 (here ) which makes it constant ( here ) because time will be constant too .
So this only tells us that V is proportional to W but not inversely proportional to I .
Hope this helps you .
