Question
![An electrical engineer is attempting to determine the currents through each branch of the circuit in the figure below. The engineer has
assumed the currents are in the directions shown in the figure. The engineer has found that the current I, is 3.57 A and the values of E
and R are unknown.
24.0 V
+
a
3.00 N-
6.00 N
What is the magnitude of the current I, (in A)?
A
Does the direction of the current I, match the direction shown in the figure?
Yes, I, points in the direction shown.
No, I, points opposite to the direction shown.
The magnitude of I, is zero, so there is no direction.
What is the magnitude of the current /, (in A)?
A
Does the direction of the current /, match the direction shown in the figure?
Yes, Ia points in the direction shown.
No, I, points opposite to the direction shown.
The magnitude of I, is zero, so there is no direction.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3693767b-b85c-4d3f-b496-33ec6c5eced0%2F98602f11-66f5-49d0-a0d6-5df36fa4cb28%2Fx73ghj2l_processed.jpeg&w=3840&q=75)
