电压规律
电压是推动电荷定向移动形成电流的原因。电流之所以能够在导线中流动,也是因为在电流中有着高电势和低电势之间的差别。这种差别叫电势差,也叫电压。换句话说。在电路中,任意两点之间的电位差称为这两点的电压。通常用字母V代表电压。
Voltage is the reason that drives the charge to move directionally to form current. The reason why the zuhehuati.89ix.comguandao.89ix.comhuanwanggui.89ix.compeidiangui.89ix.comcurrent can flow in the youle.89ix.comhuatiw.89ix.comconductor is also because there is a difference between high potential and low potential in the current. This difference is called potential difference, or voltage. Let me put it another way. In a circuit, the potential difference between any two points is called the voltage between the two points. The letter V is usually used to represent the voltage.
电源是给用电器两端提供电压的装置。电压的大小可以用电压表(符号:V)测量。
The power supply is a device that provides voltage to both ends of an electrical appliance. Voltage can be measured by a voltmeter (symbol: V).
串联电路电压规律:串联电路两端总电压等于各部分电路两端电压和。
Voltage Law of Series Circuit: The total voltage at both ends of Series Circuit is equal to the sum of the voltage at both ends of each part of Circuit.
公式:ΣU=U1+U2
Formula: U = U1 + U2
并联电路电压规律:并联电路各支路两端电压相等,且等于电源电压。
Voltage law of parallel circuit: The voltage of each branch of parallel circuit is equal and equal to the voltage of power supply.
公式:ΣU=U1=U2
Formula: U = U1 = U2
欧姆定律:U=IR(I为电流,R是电阻)但是这个公式只适用于纯电阻电路
Ohm's Law: U = IR (I is current, R is resistance), but this formula only applies to pure resistance circuits.
串联电压之关系,总压等于分压和,U=U1+U2.
The total voltage is equal to the sum of partial voltage, U = U1 + U2.
并联电压之特点,支压都等电源压,U=U1=U2
Parallel voltage characteristics, branch voltage are equal supply voltage, U = U1 = U2
