The causal relationship in the circuit is different. If there is no power supply in the circuit, even if there is voltage, the current formation will be short-lived and the voltage will not be maintained in the end. Without a power source (electromotive force current is like passive water, the voltage will not be stable. The generation and maintenance of voltage in each part of this circuit are prerequisites for the existence of electromotive force. Looking at two isolated charged conductors, they must also be There is a non-electrostatic effect to transfer charges, that is, there must be an electromotive force before there can be a stable and sustained potential difference (voltage) on the conductor.
There is a difference between change and change in a given circuit. For a given Once the power supply is produced, the electromotive force is fixed and has nothing to do with whether the external circuit is connected or not, and has nothing to do with the composition of the external circuit. However, the voltage in the circuit will change due to changes in the resistance of the external circuit, such as the increase or decrease in the number of parallel branches. When the resistance changes, the current and voltage in each part of the circuit will be redistributed, and the voltage will change. As for the circuit terminal voltage when the external circuit is disconnected, it is numerically equal to the power supply electromotive force. This is only a special result of this distribution, and it does not mean that the voltage is the electromotive force.
Electromotive force is an important physical quantity that describes the properties of a power supply. The electromotive force of a power supply is closely related to the work of non-electrostatic forces. The so-called non-electrostatic forces mainly refer to chemical forces and magnetic forces. Inside the power supply, non-electrostatic forces transfer positive charges When moving from the negative plate to the positive plate, work is done on the charge. This physical process of doing work is the essence of generating the electromotive force of the power supply. The work done by the non-electrostatic force reflects how much other forms of energy are turned into electrical energy. Therefore, inside the power supply , the process of work done by non-electrostatic force is the process of mutual conversion of energy. The electromotive force of the power supply is defined by this, that is, the ratio of the work done by the non-electrostatic force to move the positive charge from the negative pole to the positive pole and the amount of the charge is called the power of the power supply. Electromotive force.
