Is a toaster current or static electricity?
A toaster uses electrical current to generate heat and toast bread. So, the electricity used in a toaster is in the form of electrical current.
Examples of resistive heating?
In a toaster, the house current from the outlet passes through a wire with some resistance. Household electricity is supplied at a nominal 117 volts AC. If 'R' is the resistance of the wire in the toaster, then the power (heat) dissipated by the wire is E2/R = (117)2/R watts of heat. Notice that as long as the voltage remains constant, MORE resistive heat is dissipated from a SMALLER resistance.
Do toasters work because of the heating effect of an electric current?
Yes. resistance in wires within the toaster causes those wires to become very hot.
How is energy transferred from a toaster to toast?
Through the coils of the toaster
How can you tell the wires of a toaster have high Resistance?
They get red-hot, but the fuse does not blow, nor the breaker trip. Lower resistance wire fed with 120 volts might draw enormous current and get red hot, but the fuse would blow, or the breaker trip. Of course, You could always whip out your trusty multimeter and measure the resistance (allowing for change with temperature rise of course). Or, you could measure the voltage, then the current, then divide voltage by current to get resistance (at operating temperature).
How much current flows through a toaster with a resistance of 20 ohms when it is connected to a 110 volt outlet?
Ohm's Law Volts = Current x Resistance Amps = V / R 110 / 20 = 5.5 Amps
How do you apply Ohm's law to a toaster?
The wires in a toaster are composed of a metal that heats up when you pass a current through the wires. The voltage, current and resistance for the toaster obey Ohm's Law (Voltage = Current x Resistance). When the wires heat up this heat causes the bread to toast. The toast is not part of the circuit and is not involved in Ohm's Law.

How is resistance useful in a toaster?
Resistors helped the people who invented the toaster by allowing them to control current in the appliances
If you plug an electric toaster rated at 110-v into a 220-v outlet what will the outlet current in the toaster be?
It doesnt matter you will smoke it. The current in a resistive circuit is proportional to the voltage. If the voltage doubles and the resistance is the same (elements) the current will double and burn up both the elements and the toaster wiring. Look up "ohms law" for current voltage and resistance effects. Don't try it..
A toaster draws 8 A of current with a voltage of 120 V?
The voltage is the main power of a toaster!! but if the current flow is low the heat of the toaster is less heat that you expect, the 8 A is right for your toaster!!!
What is the resistance of a toaster if 120 V produces a current of 4.2 A?
Vaginal discharge drumstick
Why are resistance materials used in toasters?
Because the main purpose of a toaster is to radiate heat. In order to generate heat from electric current, resistance is required in the circuit.

Wire coild inside an electric toaster gets hot when a current flows through it the property of this wire to produce lots of heat from electricity is measured in?
ohms is ohms not used to measure resistance in the wire?
How many watts is a toaster?
You can usually find the number of volts (and watts) on a sticker under your toaster. My toaster can hold 4 pieces of toast, and uses 120 volts, but it will vary for different toaster companies, and sizes of the toaster.
Does electricity flow even if nothing is plugged into the outlet?
Yes. If you hook up your phone charger, it is using a little bit over 50% power without a phone attached. No. The voltage potential of 120 volts is at the receptacle outlet slots but to make the current flow, a resistive load is needed. In the case above the phone charger is the load. Un-plug the load and no current flow.
