19 An electric heating element is connected to a 110 V circuit and a current of 3.2 A is flowing through the element How much energy is used up during a period of 5 hours by the element?
1,760Wh
What effects of electric current is involved in the fuse breaking?
Heating Effect.
Air conditioner blows circuit breaker when heating?
If you have a heat pump and the breaker blows in heat cycle then you probably also have auxiliary electric heat which is drawing too much current because of a faulty heater element.
What are the effects of electric current?
current has five effects. 1. physical effects 2. xray effects 3. heating effects 4. chemical effects 5.magnetic effects.
Can an ac element be run on DC?
DC voltage can be used to run almost any device utilizing an electric heating element, including resistive baseboard and electric water heaters. In these applications, electrical current flowing in a heating element produces heat due to resistance.
How do you make a short circuit?
When the electrical appliances are not connected well or the cables of the electric appliances are worn out,a short circuit may occured. A short circuit affects the normal operation of electrical appliances connected to the circuit.It has very low resistance that almost all electric current would flow through it.Owing to the heating effect,an excess electric current would produce heat and thus may damage the electric appliances,or even cause a fire,if without a fuse or a circuit breaker.
How many Wh of energy is used in a 5 hr. period if an electric heating element is connected to a 110 volt circuit and a current of 3.2 A is flowing thru the elment?
352 Wh
What causes heating effect when current flows?
The resistance factors to the current flow in the circuit is what causes the heating effect in a circuit. This resistance usually comes from the load that is connected to the circuit. For example a baseboard heater is a completely resistive load and the result of the heating of the device can be used to heat a room in the home.

How does a circuit happen?
When the cables of the electrical appliances are worn out or it's not connected properly,a short circuit may occure.A short circuit has a very low resistance that almost all electric current flow through it.It'll affect the operation of the electrical appliances.Owing to the heating effect,the excess electric current would produce a large amount of heat,wihout a fuse or a circuit breaker,a fire may be occured when there's a short circuit.
Who found heating effect of electric current?
Joule showed the heating effect due to the resistence of wire which cary the current.
When does a short circuit occur?
You will get a short circuit if two uninsulated parts of the supply conductors, touch each other. You can also get a short circuit if the "hot" supply conductor touches any grounded metallic part of the system.
What happens in a circuit?
A short circuit is one that is characterized by extremely low resistance. This will result in the extremely dramatic increase of current. High current will flow until a safety device opens the circuit, or the weakest link in it burns out. And one of the two usually occurs in a moment or two.==Short Circuit happens when the cables of the electrical appliances are worn out or it's not connected properly,a short circuit may occure.A short circuit has a very low resistance that almost all electric current flow through it.It'll affect the operation of the electrical appliances.Owing to the heating effect,the excess electric current would produce a large amount of heat,wihout a fuse or a circuit breaker,a fire may be occured when there's a short circuit.
What effect of current is utilised in bulb?
Heating effect of electric current.
An electric heating element has a resistance of 16ohm and is connected to a voltage of 120v How much current will flow in the circuit?
Ohms law states that E=I * R, or voltage equals current times resistance. Therefore current equals voltage divided by resistance. 120v divided by 16 ohms equals 7.5 amps.
Heating Effect of Electric Current advantage?
Reliable, simple and safe. Heat can be regulated by changing the resistance in the circuit.
