What is the amount of current that flows in the 2-ohm resistor of the circuit as shown in the diagram below?

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.

An experimental setup consists of a battery with an EMF of 6.0 V and three resistors as shown below. Calculate the current passing through the battery and V_A- V_Bwhen the switch is (a) open and b) closed.

A student investigating how the current through a circuit depends on the polarity of a battery built the circuit shown below. Determine the amount of current that goes on each branch of the circuit.
