what is current
current is the movement of electrons , the amount of charged particles that pass a certain point every second
14 of 40
what is voltage
voltage is the energy per unit charge
15 of 40
the bigger the voltage......
the higher the current

increases it
24 of 40
how does adding impurities affect the melting point
decreases it
