All electric devices are required to have identifying plates that specify their electrical characteristics. the plate on a certain steam iron states that the iron carries a current of 6.00 a when connected to a source of 1.20 ✕ 102 v. what is the resistance of the steam iron?

Ahuge (essentially infinite) horizontal nonconducting sheet 10.0 cm thick has charge uniformly spread over both faces. the upper face carries +95.0 nc/m2 while the lower face carries -25.0 nc/ m2. what is the magnitude of the electric field at a point within the sheet 2.00 cm below the upper face? (ε0 = 8.85 × 10-12 c2/n · m2)
