Formula and explanation
The current Iᵢ through resistor Rᵢ is related to the total current I by: Iᵢ = (R(total))/(Rᵢ) I, where R(total) is the equivalent parallel resistance. Conditions: Pure resistive parallel circuit. Explanation: In a parallel circuit, the current divides inversely with the resistance. A smaller resistance gets a larger share of the current.
