Four Resistors Are Connected Across an Ideal Dc Battery with Voltage

question 375

Multiple Choice

Four resistors are connected across an ideal dc battery with voltage $V$ as shown in the figure.
Assume that all quantities shown are accurate to two significant figures. If the total current through this circuit is $I = 2.0 \mathrm {~A}$ , what is the current through the $4.0 - \Omega$ resistor?

• A) \(3.0 \mathrm {~A}\)
• B) \(1.3 \mathrm {~A}\)
• C) \(2.0 \mathrm {~A}\)
• D) \(1.0 \mathrm {~A}\)
• E) \(2.4 \mathrm {~A}\)
