Q1 (a) (i) (ii) (iii) (iv) In your own words, explain how a capacitor appears to pass alternating current while blocking direct current. A capacitor has conducting plates with area 5 x 15 mm² that are separated by a 10 µm air filled gap. What is the capacitance? What is the capacitance of a device with the same size plates as in (a)(ii) but which are separated by a um gap containing a dielectric with relative permittivity of 12? Explain what stray capacitance is and suggest how it might be avoided when a circuit is designed.
