To understand electromancy, one must learn about electric current, which can be measured using a device called an ammeter tell tale. To measure current, remove an existing wire and replace it with the ammeter tell tale, ensuring the current passes through the ammeter. Later, students should investigate a circuit, measuring how electric current affects the brightness of a light bulb and reporting their findings.

- 1. To master electromancy, you have to know about the ‘spark stream’. Use this special tell tale to measure the ‘spark stream’. Connect this tell tale by taking out a connecting wire, and putting the tell tale in its place. Remember: always put the ammeter tell tale so that the spark stream flows through it.
