Study Notes
Electric Current Fundamentals
- Electric current is the movement of electric charges within a conductor.
- Current is primarily measured in amperes, not volts; volts measure electric potential.
Circuit Types
- In a parallel circuit, the total current is equal to the sum of the currents flowing through all branches, allowing for multiple paths for the current to flow.
Types of Current
- Direct Current (DC) flows consistently in one direction, commonly used in batteries.
- Alternating Current (AC) alternates its direction periodically, commonly used in household electricity.
Resistance and Temperature
- The resistance of a conductor increases as its temperature rises, impacting current flow and efficiency.
