The membrane that surrounds a certain type of living cell has a surface area of 4.4 x 10-9 m2 and a thickness of 2.0 x 10-8 m. Assume that the membrane behaves like a parallel plate capacitor and has a dielectric constant of 5.2.
(a) The potential on the outer surface of the membrane is +52.2 mV greater than that on the inside surface. How much charge resides on the outer surface?
(b) If the charge in part (a) is due to K+ ions (charge +e), how many such ions are present on the outer surface?
A wheel rotating about a fixed axis through its center has a constant angular acceleration of 4 rad/s^2. In cerain 4s interval the wheel turns through an angle of 80 rads.
Three single-phase step-up transformers rated at 10MVA, 4.6kV/13.8kV are connected in Wye-Delta configuration. The three transformers are used to feed a 20MVA load at 0.9 p.f. With an efficiency of 96%. Find the secondary line voltage.
