What is -1.6*10-19C?
A neutral metal sphere is touched by a positively charged metal rod. The charge of the sphere will be ______ and the charge of the metal rod will be ______
What is positive, positive?
The three rules of drawing electric field lines
What is
Electric field lines are most dense around objects with the greatest amount of charge

Electric field lines never cross
If you are suspended above the ground holding on to a single power line, will you get electrocuted? Why?
No, charge only flows if there is an electric potential difference. There would be a momentary charge flow until you reach the same electric potential as the wire, at which point the charge flow would stop.
A 12V battery is connected to a series circuit R1=12 Ohms, R2=4 Ohms, R3=8 Ohms. The voltage drop across each resistor is _____
