In this lesson, you will ensure that you had fully understood the Ohm’s law.
Resistors in series and parallel
When:
- $ V $ = 10 V
- $ R_{1} $ = 10 ohm
- $ R_{2} $ = 20 ohm
- $ R_{3} $ = 40 ohm
What is $ I_{2} $, the current flowing through $ R_{2} $?
Hints
- Solve the total resistance of $ R_{2} $ and $ R_{3} $, $ R_{2and3} $ first.
- Total resistance is $ R_{total} = R_{1} + R_{2and3} $.
