Series circuit with three resistors and an ammeter

An example figure from the Circuit Diagram Generator.

A circuit diagram of a 12 V battery, an ammeter with a blank reading, and resistors R_1 2 Ω, R_2 4 Ω and R_3 6 Ω in series — A 12 V battery of two cells drives one loop through three resistors in series, R_1 of 2 Ω, R_2 of 4 Ω and R_3 of 6 Ω, and an ammeter. The ammeter’s reading is a blank line for students to work out. Resistors are drawn as US zigzags.
