Air breaks down and conducts charge as a spark if the electric field magnitude exceeds 3.00 x 106 V/m. HINT (a) Determine the maximum charge Qmax (in C) that can be stored on an air-filled parallel-plate capacitor with a plate area of 1.95 x 10-4 m2. C (b) A 44.0 HF air-filled parallel-plate capacitor stores charge Qmay. Find the potential difference across its plates (in V). V
