A linear circuit is shown below in Figure 1.


Figure 1
The elements in this circuit have the following values: R1=100Ω, R2=200Ω, R3=350Ω, V=5V, and I=0.004A.

Determine the potentials drops vA and vB across resistors R1 and R2 respectively.

What is the value of voltage vA in Volts?

incorrect
What is the value of voltage vB in Volts?

incorrect
Now let us determine if the answers you came up with satisfy the laws of physics.

What is the power (in Watts) dissipated in resistor R1?

incorrect
