6) Lightning is a spectacular example of electric current in a natural phenomenon. A typical event might transfer 2.0x10^9 Joules of energy across a potential difference of perhaps 4x10^7 V during a time interval of about 0.2 s. Use this information to estimate the total amount of charge transferred between cloud and ground? 7 A 60-V battery that can store 550 L of onoraris connected to a resistor Herr
