2nd (and much more shocking to me), I discovered much more scenarios during the search results of sentences wherever "free of" sounded correct to me and "free from" would have sounded Mistaken, than instances where "free from" sounded suitable and "free of" would've sounded wrong. First and most definitely, evaluate the phrase "free of demand":
大戸新田
环形磁路的同名端也应满足磁力线重合的条件，如下图左所示。右图为同名端在电路原理图上的符号：
In the process of composing to two persons I typed: "Are both of you free?" and was right away termed out by my grammar checker which advised I ought to compose: "Is both of you free?"
从全耦合变压器的等效电路中不难看出，一次线圈作为自感，与负载阻抗 承载相同的输入电压 ，在输入电压一定的情况下，一次线圈的感值越大，励磁电流 就越小，分配到负载 的电流就越多。
The expression "free, white, and 20-1" goes back again at the very least a tiny bit farther then 1854, when the very first as a result of third editions of
[Edit: From the comments over, FumbleFingers mentions “goodies:” it’s primarily synonymous with “swag” and is another awesome phrase to use to speak up the advertising materials you’re gifting away. Swag bags are often known as “goody” or “goodie bags.”]
Of the various thrilling accounts of lifestyle from the trenches beneath fireplace which have been released in the final calendar year or two, none is much more vivid and stirring into the blood compared to story with the expertise of the hardy son of your Blue Grass Point out who decided in October, 1915, that getting free, white, and twenty-one particular, it absolutely was his manifest responsibility to strike a blow for democracy. So he traveled in scorching haste to Canada and enlisted while in the Canadian Grenadier Guards.
我们对互感电路进行分析时，另一个线圈对本线圈的互感作用可等效为一个额外的电压源（电动势，方向由同名端规则判定），而本线圈的自感作用可看作是一个感抗器件，如下图，左边的电路可转化为右边的电路模型进行分析求解：
東大戸村 click here ← 大戸村・大戸川村・山之辺村・森戸村・片野村・上小川村・関村・新寺村・玉造村
Thinking that he was an old wanderer from his grey beard, they dined him and as Lem failed to tip his duke they gave him a buck and two a long time subscription for your Hog Cholera Month to month
为什么现在的孩子很难开心，甚至就连出去旅游都兴趣缺缺，只想回酒店吹空调吃零食？
显然，理想变压器拥有全耦合变压器的所有特征，比如最基本的电压比与匝数比的关系：
@ShreevatsaR, @Kosmonaut: I think that Probably the example I used was not the top. I even now think that The 2 phenomena are connected, but possibly only simply because they both revolve all-around perceived ambiguities of plurality.
