Vishay’s ISOA200 thick-film power resistors with optional NTC thermistor and phase-change thermal interface material saves ...

When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor ... For the circuit above, the formula for finding the total resistance ...

frac{1}{R}=\frac{1}{R}_{1}+\frac{1}{R}_{2}\) To calculate the total resistance of three resistors connected in parallel, we add a third resistor to the equation (and so on).
