Answer :

Final answer:

In a parallel circuit, understanding the voltage rule, current rule, and resistance rule are essential for calculations.


Explanation:

The three basic rules of parallel circuit calculations are:

  1. Voltage Rule: Voltage is equal across all components in a parallel circuit.
  2. Current Rule: Total current in the circuit equals the sum of the currents through each resistor.
  3. Resistance Rule: In a parallel circuit, the total resistance is calculated differently compared to series circuits. The reciprocal of the total resistance is equal to the sum of the reciprocals of each individual resistor's resistance.
