When available, open the Introduction to Mastering assignment and select the Entering Series and Parallel Connections item. This assignment provides practice items for different kinds of questions.

You can usually return to this assignment anytime during the course, even after its due date. If you completed this assignment, you can usually rework its items for practice.

1. Point in the answer box to make it active.

2. Enter letters, numbers, spaces, parentheses, and the symbols for series (+) and/or parallel (||). For example: (L1||L2)+C1||C2 + (R1+R2)||(L3+L4)
   
   • Parallel connections (||) are interpreted before serial connections (+).
     For example, L1 || L2 + C1 || C2 is interpreted as (L1 || L2) + (C1 || C2), not L1 || (L2+C1) || C2.
   • Use lowercase letters to save time.
     Mastering automatically displays your alphabetic characters in uppercase.
   • A red parenthesis means something is missing from your expression.
     Check for any missing series symbol, parallel symbol, or an open or close parenthesis.
     

Use the toolbar options — Point in the answer box, then choose  series or  parallel.

Edit from your keyboard — You can copy, cut and paste selected parts of the expression using standard keystrokes. To navigate within your expression, use the left and right arrow keys.
