Question

(Figure 1)

What are the magnitude and direction of the current in the 20 Ω resistor in (Figure 1)?

Express your answer with the appropriate units. Enter positive value if the current is clockwise and negative value if the current is counterclockwise.

 

Answer 1

Net current through circuit

\(\mathrm{i}=\mathrm{V} / \mathrm{R}\)

\(i=(9-6) /(10+20)\)

\(\mathrm{i}=0.1 \mathrm{~A}\)

Directed in clockwise way.
