Two resistors are connected in parallel, one R1 = 75 ohm, the other R2 = 300 ohm. Calculate total resistance

Given: R1 = 75 Ohm, R2 = 300 Ohm.

Find: Rtot.

Solution:

When the conductors are connected in parallel, the formula for finding the total resistance applies: Rtot = R1 * R2 / (R1 + R2),

means:

Rtot = 75 * 300 / (75 + 300) Ohm,

Rtot = 22500/375 Ohm,

Rtot = 60 Ohm.

Answer: Rtot = 60 Ohm.
