An electric heater is constructed by applying a potential difference of 120 v to a nichrome wire that has a total resistance of 6.00 . find the current carried by the wire and the power rating of the heater.

The current carried by the wire and the power rating of the heater are 20 A and 2400 W respectively.

Given data:

The potential difference across the electric heater is, V' = 120 V.

The total resistance of the nichrome wire is, .

First we need to apply the Ohm's law to find the current through the wire. The expression for the Ohm's law is given as,

Now, the expression for the electric power through the heater is given as,

Thus, we can conclude that the current carried by the wire and the power rating of the heater are 20 A and 2400 W respectively.

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h
