Insights
- Electric current is the flow of charges, moving from higher to lower potential, measured in amperes. Resistance, which opposes current flow, is influenced by factors like length, cross-section, resistivity, and temperature, following Ohm's Law and impacting circuit behavior.
- Power in electrical circuits is the rate of energy consumption, with devices drawing more current and consuming more energy having higher power. Understanding power, measured in watts, and energy units like kilowatt-hour (kWh) is essential for managing electricity consumption effectively.
