Solution for (a)Д®ntering the given values for the emf, load resistance, and internal resistance into the expression above yields Once the current is found, the terminal voltage can be calculated using the equation V = emf в€’ Ir.В Once current is found, the power dissipated by a resistor can also be found. The analysis above gave an expression for current when internal resistance is taken into account. 500 О©, find the current, terminal voltage, and power dissipated by a 0.500-О© load. (b) What is the terminal voltage when connected to a 0.500-О© load? (c) What power does the 0.500-О© load dissipate? (d) If the internal resistance grows to 0. (a) Calculate its terminal voltage when connected to a 10.0-О© load. Note also that since the chemical reactions involve substances with resistance, it is not possible to create the emf without an internal resistance.ДЄ certain battery has a 12.0-V emf and an internal resistance of 0.100 О©. Under many circumstances, these electrons come from the anode, flow through a resistance, and return to the cathode. Note that the reaction will not take place unless there is a complete circuit to allow two electrons to be supplied to the cathode.

In short, a separation of charge has been driven by a chemical reaction.

This leaves the cathode positively charged, because it has lost two electrons. Two electrons are placed on the anode, making it negative, provided that the cathode supplied two electrons. Figure 4В shows the result of a single chemical reaction. The details of the chemical reaction are left to the reader to pursue in a chemistry text, but their results at the molecular level help explain the potential created by the battery. Sulfuric acid conducts the charge as well as participating in the chemical reaction. The lead oxide plates are connected to the positive or cathode terminal of the cell. Chemical reactions in a lead-acid cell separate charge, sending negative charge to the anode, which is connected to the lead plates. The reason for the decrease in output voltage for depleted or overloaded batteries is that all voltage sources have two fundamental parts-a source of electrical energy and an internal resistance. This implies that the batteryвЂ™s output voltage is reduced by the overload. Furthermore, if you connect an excessive number of 12-V lights in parallel to a car battery, they will be dim even when the battery is fresh and even if the wires to the lights have very low resistance. Why donвЂ™t they simply blink off when the batteryвЂ™s energy is gone? Their gradual dimming implies that battery output voltage decreases as the battery is depleted. When you forget to turn off your car lights, they slowly dim as the battery runs down. Explain why it is beneficial to use more than one voltage source connected in parallel.Describe what happens to the terminal voltage, current, and power delivered to a load as internal resistance of the voltage source increases (due to aging of batteries, for example).Compare and contrast the voltage and the electromagnetic force of an electric power source.
