The water in the river and in a hose relates to the relationship between voltage current and resistance in a circuit. R is resistance measured in ohm. Relationship Energy Transferred Current Voltage Time Power 6 Energy Transfer Relationship Energy For a capacitor the current is. . Current Voltage and Power. The next plot clarifies the relationship between collector current and forward bias of the BC junction. As suggested by Ohms Law the relationship. All materials are made up from. In the water-hose analogy the pressure from the tap and. From the current voltage relationship in a capacitor. Before we can answer this question in more detail we need to understand exactly what is a resistor. I is current measured in ampere. The difference between Voltage and current is a very basic concept and can be understood by the simple concept of cause and effect. This concept says that two quantities
