How did you get these two equations?Angie K. said:
For one thing, you forgot to multiply the internal resistance by the current to get the voltage drop.Angie K. said:
I'm seeing a mix of voltage and resistance terms, some resistances multiplied by currents and some not. So as written those equations cannot be correct. You are summing potential changes around the loop, so any resistor value must be multiplied by a current in order to realize its potential change (Ohm's Law). Perhaps you could group the resistance terms for given currents in parentheses?Angie K. said:
Angie K. said:
Aren't 2.48 and 8 and 10 all resistances? What currents multiply them? I see only two voltage sources in the loop (both 12 V).
Again, I don't see currents multiplying each resistance.

Kirchhoff's Laws are two principles used in circuit analysis to determine the currents and voltages in a circuit. The first law, also known as Kirchhoff's Current Law (KCL), states that the sum of all currents entering a node in a circuit is equal to the sum of all currents leaving that node. The second law, also known as Kirchhoff's Voltage Law (KVL), states that the sum of all voltages around a closed loop in a circuit is equal to zero.
Kirchhoff's Laws provide a systematic approach to analyzing a circuit and determining the currents flowing through it. By applying KCL and KVL to different parts of a circuit, we can create a system of equations that can be solved to find the currents in each branch of the circuit.
In a series circuit, all components are connected in a single loop, so the same current flows through each component. In a parallel circuit, the components are connected in multiple branches, so the total current is divided among the branches. Kirchhoff's Laws can be applied to both types of circuits, but the equations used may differ.
Kirchhoff's Laws are based on the principles of conservation of charge and energy, so they can be applied to any circuit regardless of its linearity or complexity. However, the equations used to solve non-linear circuits may be more complex and require advanced mathematical techniques.
Kirchhoff's Laws assume ideal conditions, such as constant voltage sources and ideal circuit components. In real-world circuits, these conditions may not hold true, which can lead to discrepancies between the calculated and actual currents. Additionally, Kirchhoff's Laws only apply to DC circuits, and different principles must be used for AC circuits.
