The current flowing through a lamp is 1.5 a. it is plugged into a 120-v outlet. what is the resistance of the lamp

Explanation:

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.
