An iron is going to use more electrical current than a kettle. The iron needs to be plugged in to stay hot. The kettle is usually unplugged after the contents reach the right temperature.

The electric current drawn is the same for both appliances, 13 amps if they are both 13-amp devices.
However an iron is usually a lower-power device of about 1 kW that would draw 4 amps on a 240 v supply, and its thermostat would operate to control the current so that it doesn't overheat.
Some kettles have a 3-kW element which would draw 13 amps, but kettles are used only now and then. So both devices do not use a lot of energy.

What type of an electrical circuit has more than one current branch?
A parallel circuit is an electrical circuit that has more than one current branch.
Why is copper used for electrical wiring instead of iron?
Copper wires conduct electricity much better than iron. This is because electric current passes through copper with very less resistance. it is also more ductile and malleable.
Can a ground leakage damage electrical appliances?
A ground leakage can damage electrical appliances. When there is a current leakage, it causes the appliance to draw more current through thecircuit, hence produces excess heat. This can damage the appliances.
Why is aluminum a better conducter of electricity than sodium?
'Voltage' isn't 'conducted'. Voltage can be thought of as 'electrical pressure' which, when applied across opposite ends of a conductor will cause a CURRENT to flow along that conductor. So your question should really be asking, why aluminium conducts a greater CURRENT than iron. The answer is simple. Aluminium is a better 'conductor' than iron. In other words iron resists the flow of current more than aluminium does. Or to express this in another way, iron offers a greater RESISTANCE to the flow of current. Resistance is a natural property of a conductor, with some conductors have more, or less, resistance than other conductors. The best conductor, i.e. the one with the least resistance, is silver -closely followed by copper. Iron is a relatively poor conductor in comparison with silver, copper, or aluminium.
Does Australia have 50 Hz electrical current?
Yes.For more information see the answer to the Related Question shown below.
What is electrical conductance?
Electrical conductivity is the measure of a material accommodates the transport of electric charge. Its SI derived unit is the siemens per metre, (A2s3m−3kg−1) (named after Werner von Siemens) or, more simply, Sm−1. It is the ratio of the current density to the electric field strength or, in more practical terms, is equivalent to the electrical conductance measured between opposite faces of a 1-metre cube of the material under test

What is kettle's efficiency?
Kettle efficiency refers to how effectively a kettle can convert electrical energy into heat energy to boil water. A kettle's efficiency can be influenced by factors such as the material of the kettle, its insulation, and the design of the heating element. Kettles with higher efficiency tend to boil water faster and use less electricity.
What is the energy input for a kettle?
Electrical energy transformed into Thermal energy (heat) and Mechanical energy (sound)
Why is copper usually used to make electrical wires instead of iron?
it is cheaper,conduct electricity better then iron,more ductile and maleable
What happens to electrical current and voltage in a parallel circuit as you add more bulbs?
Voltage remains constant; current increases.
Do aparallel circuit contanins two or more electrical paths for current to flow?
yes
Why do factors effect electromagnets?
The factors that affect the power of electromagnets are: the current (amperes), the amount of coils, and whether a soft iron core is present. These affect the electromagnet because the current is what provided the electrical energy which created the magnetic field, and so the greater the current, the stronger the magnetic field; the amount of coils is a measure of the resistance provided by the wire, and so the greater that is, the more electrical energy is being used to strengthen the magnetic field; finally, the soft iron core further strengthens the magnetic field as it can be temporarily magnified, so it will become a magnet itself.
What makes a current lower and generates more heat?
The resistance of the electrical conductor, eg a wire, reduces the current which can flow in the circuit. The remaining current which does flow generates heat, representing the electrical energy which has been lost in overcoming the resistance.
What can take more eletricity wood or rubber?
the wood because it has more water in it which can carry a better electrical current
What happens and why to a soft iron if it remains in the core with the current flowing for more than a few minutes?
the current remains constant as more magnetic lines are free
