Question 10

In the given circuit, emf_A = 10 V and the current I_C = (1/7) A in the direction shown. Calculate the current in R_B and the magnitude of emf_B.

• A. 1/10 A, downward; emf_B = 5 V
• B. 1/14 A, upward; emf_B = 7 V
• C. 1/14 A, downward; emf_B = 5 V
• D. 1/10 A, upward; emf_B = 10 V
• E. 1/7 A, downward; emf_B = 7 V
