Yea sorry I just looked back at my notes and a video in my language. Unfortunately, I moved from Hong Kong and taking a physics class in English. English isn't my strongest languageDr Transport said:you need to write down the two voltage loop equations...
To determine the currents I1, I2, and I3, you will need to use Kirchhoff's Current Law (KCL) and Ohm's Law. KCL states that the sum of all currents entering a node must equal the sum of all currents leaving the node. Ohm's Law states that current (I) is equal to voltage (V) divided by resistance (R). By setting up a system of equations using KCL and Ohm's Law, you can solve for the unknown currents I1, I2, and I3.
In order to determine the currents I1, I2, and I3, you will need to know the values of the resistors in the circuit and the voltage sources. You may also need to know the direction of the current flow in the circuit, which can be determined by the direction of the voltage sources and the orientation of the resistors.
Yes, you can use a calculator to determine the currents I1, I2, and I3. However, you will need to set up the equations correctly and use the correct units for the values of resistance and voltage. It is also important to double check your calculations to ensure accuracy.
If there are multiple voltage sources in the circuit, you will need to apply KCL and Ohm's Law to each individual node in the circuit. This will result in a system of equations with multiple unknown currents, which can then be solved using algebraic methods.
No, there is no specific order in which you should solve for the currents I1, I2, and I3. However, it may be helpful to start at a node with the most known values or the simplest equations. It is also important to label your equations and unknown currents correctly to avoid confusion.
