Electricity Concepts

Basic Terms

  • Volt (V): Unit of voltage, the force to push electrons.

  • Ampere (A): Unit of current, the flow rate of electric charge.

  • Watt (W): Unit of power, calculated as volts multiplied by amps.

  • Ohm (Ω): Unit of resistance, opposition to current flow.

Key Units of Electricity

  • Voltage (V)

  • Current (I)

  • Power (P)

  • Resistance (R)

Electrical Components

Transistor and Diode

  • Transistor: Regulates current/voltage; acts as a switch.

  • Diode: Conducts electricity in one direction (anode and cathode).

Maintenance Concepts

Importance of Maintenance

  • Corrects faults, improves designs, implements enhancements.

Types of Maintenance

  1. Preventive Maintenance: Proactive checks and cleaning to avoid failures.

  2. Corrective Maintenance: Addressing existing problems.

  3. Improvement Maintenance: Upgrading processes or hardware.
