This document discusses resistance and Ohm's Law in electrical circuits. It begins with a sample dialogue between two characters, Sofyan and Mr. Farid, about resistance. It then covers key topics about resistors, including their symbol, parts, and factors that affect resistance. Ohm's Law is introduced, defined as I=E/R, where I is current, E is voltage, and R is resistance. Examples are provided to demonstrate how to use Ohm's Law to calculate current or resistance given the other two values. The document concludes with exercises for students to answer questions, identify true/false statements, formulate main ideas, look up definitions, and translate the text to Indonesian.
