Question B-005-006-007

Which combination of resistors could make up a 50 ohms dummy load capable of safely dissipating 5 watts?

Correct Answer

Four 2-watt 200 ohms resistors in parallel

Explanation

Four 200 Ω resistors in parallel give a total resistance of 200 Ω / 4 = 50 Ω. Each is rated for 2 W, so the total power handling capacity is 4 * 2 W = 8 W, which is safely above the required 5 W.
