    Green Pea Discharge: How Much Charge Can It Hold?

    I don't have a clue on where to start this as i don't know what other figures to use. Dry air will break down and generate a spark if the electric field exceeds 3x106N/C. How much charge could be packed onto a green pea (diameter 0.75cm) before the pea spontaneously discharges?

    Transformer Winding Calculations: Primary to Secondary Current and Voltage

    Please can someone help me with his question A transformer has a 120-turn primary winding and an 1800-turn secondary winding. A current of 10A flows in the primary winding when the potential difference of 550V is placed across it. Find the current in the secondary winding and the potential...
