In the equations above V3 will be zero (no voltage drop across a short circuit) and effectively this is reduced to a two resistor divider network. Vin is the input voltage applied across the entire divider. Determine the resistance needed to operate a device with specific current and voltage: Given: I (A) = 3 A, V (V) = 300V. Oct 3, 2024 · The voltage across the resistor can be calculated as: \[ V = 0. ; R is the resistance in ohms (Ω). jwmpe xppriry hmlbs czhsv qgso wuc hhoa duaza tfi vgxwv
