AI Customer ServiceWhat is power dissipation in a sliding resistor? Power dissipation in a sliding resistor refers to the amount of energy that is converted to heat as the resistor slides over a surface, causing friction and resistance. How
AI Customer ServiceOnce the charges have crossed the resistor, the electric potential in the wire is again constant until they reach the other terminal of the battery. Thus, in this simple circuit, the electric potential difference across the resistor is the same as the potential difference across the terminals of the battery.
When no resistance is connected across a real battery, the potential difference across its terminals is measured to be 6V 6 V. When a R = 2Ω R = 2 Ω resistor is connected across the battery, a current of 2A 2 A is measured through the resistor.
In practice, this is usually accounted for when a circuit diagram is made (i.e. any resistors include the resistance of the wires connected to it). Figure 20.1.4 20.1. 4: A simple circuit, showing a 9 V 9 V battery and a 2Ω 2 Ω resistor.
If the electrodes of the cell are connected with a very low resistance resistor, the resulting current will be too large for the potential difference to be maintained. Most electric cells work in similar ways, although the chemical reactions can be much more complex.
If a positive charges enters the negative terminal of a battery and exits the positive terminal, its potential energy will have increased. If that charge then enters a resistor, its potential energy will decrease as it moves through the resistor, since the charge will “use” its potential energy to heat up the resistor.
Thinking about two batteries next to each other, linked by one wire-- there is no voltage between the two batteries, so there is no force to drive electrons. In each battery, the electrostatic force balances the chemical force, and the battery stays at steady state.
