Find io from the graph. Find the time constant RC = io/e where e = 2.71828.
From RC you can find R.
 
  • #3
We know from the theory that the current vs time function is:

[tex]I(t)=I_0e^{\frac{t}{RC}}[/tex]

Now you can see that when the current is the e-th part of I_0 i.e. I=I_0/e then the time is [tex]t=RC[/tex]

Now try to calculate R.
 

FAQ: Solving Circuits Problem - Get Help Now!

What is a circuit and how does it work?

A circuit is a closed loop or path through which electricity can flow. It is made up of various components, such as wires, resistors, capacitors, and switches, that are connected in a specific way to control the flow of electricity. When a power source, such as a battery, is connected to a circuit, it creates a voltage difference that causes current to flow through the circuit, powering any devices connected to it.

How do you solve circuit problems?

To solve a circuit problem, you must first understand the basic principles of circuit analysis, such as Ohm's law and Kirchhoff's laws. Then, you can use techniques like series and parallel circuit analysis, node and mesh analysis, and the superposition theorem to simplify the circuit and calculate the values of unknown components. Additionally, using tools like circuit simulators can also help in solving complex circuits.

What are the most common challenges in solving circuit problems?

Some of the most common challenges in solving circuit problems include identifying the type of circuit (series, parallel, or combination), dealing with non-linear components, and simplifying complex circuits. It is also important to be accurate in measurements and calculations, as even a small mistake can drastically affect the results.

How can I get help with solving circuit problems?

There are various resources available for getting help with solving circuit problems. You can consult textbooks, online tutorials, and video lectures for a better understanding of circuit analysis techniques. Additionally, seeking help from a teacher, tutor, or peer who is knowledgeable in circuit analysis can also be beneficial.

What are some tips for solving circuit problems efficiently?

Some tips for solving circuit problems efficiently include first drawing a clear and accurate circuit diagram, labeling all components and values, and properly applying the circuit analysis techniques. It is also important to double check all calculations and use appropriate units. Additionally, practicing regularly and understanding the underlying principles of circuit analysis can help in solving problems more efficiently.
