Problem

A 1.0 μF1.0\,\mu\text{F} parallel-plate capacitor with plate separation 0.50 mm0.50\,\text{mm} and a 4.0 μF4.0\,\mu\text{F} parallel-plate capacitor with plate separation 0.25 mm0.25\,\text{mm} are connected in series to a 12 V12\,\text{V} battery. After the circuit reaches steady state, which capacitor experiences the greater electric-field magnitude between its plates, and approximately what is that field? (a) The 4.0 μF4.0\,\mu\text{F} capacitor; about 4×104 V/m4\times10^{4}\,\text{V/m} (b) The 1.0 μF1.0\,\mu\text{F} capacitor; about 3×104 V/m3\times10^{4}\,\text{V/m} (c) The 1.0 μF1.0\,\mu\text{F} capacitor; about 2×104 V/m2\times10^{4}\,\text{V/m} (d) The 4.0 μF4.0\,\mu\text{F} capacitor; about 1×104 V/m1\times10^{4}\,\text{V/m}
