2.7a 110 v heating element in a stove can boil a standard-size pot of water in 1.2 minutes, consuming a total of 136 kjof energy. determine the resistance of the heating element andthe current flowing through it.

Resistance of the heating element: 6.4 ohm

Current flow:17.17 amperes

Explanation:

First we need to convert from Joules to Watts, in order to do that we need the time in seconds:

Then apply the formula:

Clearing watts from the equation:

Then, we know the input voltaje is 110V, and Watts= Voltage* Current.

Finally Voltaje over Current= Resistance, from ohm's law

electrical power

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
