Electrical Current Relationships in Circuits
The image shows three separate equations related to electrical circuits.
<p>A. \(\Sigma I_{masuk} = \Sigma I_{keluar}\)</p>
<p>This equation represents Kirchhoff's Current Law (KCL), which states that the total current entering a junction in a circuit must equal the total current leaving the junction. This is due to the conservation of charge.</p>
<p>B. \(I_1 = I_2 = I_3\)</p>
<p>This equation suggests that the current through each component in a series circuit is the same. In a series circuit, there is only one path for current flow, so the current is constant throughout the circuit.</p>
<p>C. \(I = \frac{V}{R}\)</p>
<p>This equation is derived from Ohm's Law, which states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. This is the formula used to calculate the current when the voltage and resistance are known.</p>
