Kirchhoff's Junction Rule
27. Resistors & DC Circuits / Kirchhoff's Junction Rule / Problem 2
In an electrical circuit, a lightbulb with a uniform resistance R is connected in series with two resistors, R1 and R2. When a 12-V battery is connected to the circuit, the lightbulb dissipates 6.4 W of power. Given that R1 = 2.0 Ω and R2 = 3.0 Ω, determine the current passing through the lightbulb.
