1. Calculate the capacitance between two parallel plates, each of which is 100 sq. Inches and 2 mm apart in air. 2. A capacitor is charged with 0.23 J of energy at a voltage of 48V. What is its capacitance? 3. A 50-uF capacitor is initially charged. Determine the initial charge of the 50-uF capacitor if the charge transferred to a 100-uF capacitor, when connected in parallel, is 200-uC.
