Hi, does applying resistance to a potential divider affect the output voltage? For example, if I were to put resistor R midway across a variable resistor would output voltage still = (R1/R1 + R2) x E? Picture is an example of what I mean, for example would the Pd across R still equal the Pd if R was replaced with a voltmeter or would rules change to account for the added resistance. Perhaps I am misunderstanding the concept of potential dividers but responses would be great.
P. A I edited this question in response to a comment and I apologise if this question sounds stupid because I couldn't find any information about this.
