The current in a lamp is 0.5 amps when plugged into a standard 110 V wall outlet. What is the resistance of the lamp when it is plugged into the standard wall outlet? *

According to ohm's law, current flowing through a conductor is directly proportional to the voltage over resistance.

Mathematically,       I =

where,     I = current

              V = voltage

               R = resistance

It is given that value of voltage is 120 V and current is 1.5 ampere. Therefore, calculate the resistance as follows.

                           I =

or,                         R =

                               =

                               = 80 volts per ampere

                              = 80 ohms

Hence, resistance of the lamp is 80 ohms.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
