Web10 Jul 2024 · Electromotive force is the electric potential generated by either a electrochemical cell or a changing magnetic field. It is also known as voltage.It is electrical action produced by a non-electrical source, such as a battery (converts chemical energy to electrical energy) or generator (converts mechanical energy into electrical energy). WebA variable resistor is a resistor of which the electric resistance value can be adjusted. A variable resistor is in essence an electro-mechanical transducer and normally works by sliding a contact (wiper) over a resistive element. When a variable resistor is used as a potential divider by using 3 terminals it is called a potentiometer. unpaid compensation beneficiary form
