1. What does P = E x I stand for?
Stands for direct current and it is when electrons move in one direction.
E stands for voltage in volts - I stands for current in amperes - and P stands for power in watts.
The basic unit used to measure electrical power.
When current flows - the resulting work is energy. Current flow tends to heat whatever its moving through - which is a useful characteristic of an appliance.

2. What is going on in a wire conductor with free electrons?
