... shown in Fig. 2-4. The larger the current through the resistor, the greater the EMF across the resistor. In general, this EMF is directly proportional to the current through the resistor. This ... matter, whether it is solid, liquid, or gas, is made of molecules. These particlesare always moving. The speed with which they move depends on the temperature. The hotter the temperature, the more ... charge carriers, there will be a current of 1A. If the re-sistance is doubled, the current is cut in half. If the resistance is cut in half, the currentdoubles. Therefore, the current flow,...
