Hi! I connect 9 volts to a 1 ohm resistor and thought I would get I = U/R = 9 A. But when I connect the ampmeter, I cannot read anything! Where is the problem?
You can look up the Equivalent Series Resistance of the battery. A battery can be considered an ideal voltage source (which could provide an infinite amount of current) in series with a resistor. This series resistor limits the total current the battery can deliver. If you look up the ESR, you can calculate the maximum possible current.danne89 said:But how can I determ from the battery how many amps it will deliver?
Glad we could steer you in the right direction. Though I don't quite understand what you mean by "seems to work" (My circuits either work or don't work). Do you mean you are fuzzy about how your circuit presently works?danne89 said:Now it seems to work. Thanks
The purpose of troubleshooting a 9V and 1 Ohm resistor connection is to identify and resolve any issues or problems that may be preventing the connection from functioning properly. This could include issues such as loose or damaged wires, incorrect wiring, or faulty components.
Some common problems that can occur with a 9V and 1 Ohm resistor connection include a lack of power or voltage, incorrect resistance readings, and short circuits. These issues can be caused by a variety of factors such as faulty components, incorrect wiring, or poor connections.
To troubleshoot a 9V and 1 Ohm resistor connection, you can follow a few steps. First, check all of the connections and make sure they are secure and free of any damage. Next, use a multimeter to test the voltage and resistance readings at various points in the circuit. If there is a problem, the multimeter will help you pinpoint where the issue is occurring. Finally, try replacing any potentially faulty components to see if that resolves the issue.
If you are unable to find the source of the problem with your 9V and 1 Ohm resistor connection, it may be helpful to consult a professional or someone with more experience in electronics. They may be able to offer additional troubleshooting tips or help you identify the issue more quickly.
To prevent future issues with your 9V and 1 Ohm resistor connection, make sure to use high-quality components and follow proper wiring techniques. Regularly checking and maintaining your connections can also help prevent any potential problems. Additionally, it may be helpful to consult online resources or seek advice from experts in the field for tips on troubleshooting and preventing issues with your specific circuit.
