Given that v = 7V . compute the voltage across the 3 ohm resistor in the figure.

Question

Given that v = 7V . compute the voltage across the 3 ohm resistor in the figure. (figure 1.) Express your answer to two significant figures and include the appropriate units. Find the voltage across the current source in the figure. Express your answer to two significant figures and include the appropriate units. Find the power of the current source in the figure. Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

A) current through 3 ohm resistor = 1 A => voltage across = 3 * 1 = 3V B) voltage source = 7v => voltage across current source = 7 - 3 = 4V C) power = VI = 4 * 1 = 4
