Assume that all the resistors are 30.0-ohm. Find the equivalent resistance.

Req = 1/30 + 1/30 + 1/30
= 10-ohm

Assumer that each resistor dissipates 120 mW. Find the total dissipation.

-Is this formula P= I^2R to use for this problem? By the way, what is dissipation?

1 answer

Dissipation is the generation of heat power in resistors.

Total dissipation is 3 x 120 mW
