hot plate is plugged into the wall socket and a current I of 5A flows through it. Enjoy your tea! What in Ohms is the resistance of the hot plate?
Using ohms law resistance of hot plate is voltage divided by current.
Calculation is as shown below.

A 1500-W heater is designed to be plugged into a 120-Voutlet. What current will flow through the heatingcoil when the heater is plugged in? I = A What is ,the resistance of the heater? R = ohms How long does it take to raise thetemperature of the air in a good-sized living room by ? Note that the specific heat of air is 1006 and the density of air is . t= minutes
A 15-W compact fluorescent light bulb is used in a lamp plugged into a 120-V wall socket. You can assume the lamp itself has zero resistance. Find (a) the resistance of the light bulb, (b) the maximum current through the bulb, and (c) the maximum power used by the light bulb. Also, if the frequency of the electricity is the typical household value of f = 60 Hz, what are the first two times that the current going through the...
4. Consider a 60W light bulb plugged into a 120V socket, and a 100W light bulb plugged into another 120V socket Recall that a bulb's brightness is related to the amount of power (in watts) that is dissipated as heat and light. a Through which light bulb is more current passing? b. Which light bulb filament has more resistance? c. If these light bulbs were connected together in series into the same 120V outlet, which light bulb will be brighter?...
A light bulb is connected to a 120.0-V wall socket. The current in the bulb depends on the time t according to the relation I = (0.781 A) sin [(205 rad/s)t]. (a) What is the frequency of the alternating current? (b) Determine the resistance of the bulb's filament. (c) What is the average power delivered to the light bulb?
A light bulb is connected to a 120.0-V wall socket. The current in the bulb depends on the time t according to the relation I = (0.788 A) sin [(469 rad/s)t]. (a) What is the frequency of the alternating current? (b) Determine the resistance of the bulb's filament. (c) What is the average power delivered to the light bulb?
