Understanding Electrical Units
Electrical calculations involve several key units. Voltage (measured in Volts) represents the electrical potential difference. Current (measured in Amperes or Amps) represents the flow of electrical charge. Power (measured in Watts) represents the rate of energy transfer. Resistance (measured in Ohms) represents opposition to current flow.
AC vs DC Circuits
Direct Current (DC) flows in one direction and is commonly used in batteries and electronics. Alternating Current (AC) periodically reverses direction and is used in household and industrial power systems. AC calculations often require considering the power factor, which represents the efficiency of power usage.
