Voltage, power and energy
Homework 2 assignment
Voltage represents the energy available
to move electrons
The voltage between two points is the energy w (in
joules (J) or kWh) needed to move a charg
GENERAL:
SERIES: current is same in series but voltages isnt so we have voltage divider
PARALLEL: voltages is same in parallel but current isnt so we have current divider
e=-1.602X10-19C
CURRENT:
1C=6.24X1018 electrons
1 ampere=1 coulomb/second
