Acircuit maintains a constant resistance. if the current in the circuit is doubled, what is the effect on the power dissipated by the circuit? the power dissipated is doubled. the power dissipated is quadrupled. the power dissipated is reduced by a factor of 2.the power dissipated remains constant. the power dissipated is reduced by a factor of 4.

Acarpenter builds an exterior house wall with a layer of wood 2.9 cm thick on the outside and a layer of styrofoam insulation 2.3 cm thick on the inside wall surface. the wood has k=0.080w/(m⋅k), and the styrofoam has k= 0.010 w/(m⋅k). the interior surface temperature is 19.0 ∘c , and the exterior surface temperature is -15.0 ∘c . a.)what is the temperature at the plane where the wood meets the styrofoam? celsius b.)what is the rate of heat flow per square meter through this wall? /m^2
