(d) It depends on the material of the resistor 电阻随温度变化的规律与电阻材料的性质密切相关: 1. **金属导体**(如铜、铝):温度升高时,原子热振动加剧,导致自由电子移动受阻,电阻**增大**(选项a)。 2. **半导体**(如硅、锗):温度升高时,载流子(电子和空穴)浓度增加,导电能力增强,电阻**减小**(...
Voltage is an indicator of the ability to move electricity. The concept is closely related to other concepts such as potential difference, current, and resistance, so it's important to develop an overall understanding of the subject. To measure voltage, you’ll need a multimeter. Multimeters are...
Also, in the parallel circuit, the equivalent resistance is always less than any of the individual resistances. Current Divider Formula A general formula for a current divider is given by Where, = Current through any resistor in the parallel circuit = = Total current of the circuit = = Eq...
Fig.1: Resistance and current can be compared to the flow of a river If you want more current to flow at a given resistance value, you can accomplish that by raising the voltage. Power is generally calculated by multiplying current (A) by voltage (V), yielding a result that is expressed...
