Can you always put numbers directly into an expression which has the delta triangle against its variables? For example Faraday's Law is always shown with the delta triangle on top and bottom yet these are dropped when you use it for calculations; which leaves me wondering why they are there in the first place, since you never find them (for example) in Ohms Law.(adsbygoogle = window.adsbygoogle || []).push({});

Thanks.
