    1. Identify the resistance values of all resistors in the parallel circuit (e.g., R₁, R₂, ..., Rn).

    2. Use the formula for total resistance in parallel: 1/R_total = 1/R₁ + 1/R₂ + ... + 1/Rn.

    3. Calculate the reciprocal of each resistor value (e.g., 1/R₁, 1/R₂, etc.).

    4. Add all the reciprocal values together.

    5. Take the reciprocal of the sum to find the total resistance: R_total = 1 / (Sum of reciprocals).

    6. Ensure the result is in Ohms (Ω) for consistency.

    For example, if R₁ = 4 Ω and R₂ = 6 Ω, the calculation would be: 1/R_total = 1/4 + 1/6 = 3/12 + 2/12 = 5/12 R_total = 12/5 = 2.4 Ω.
