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?

If an electric heating element is connected to a 110 volt circuit and a current of 3.2 amp is flowing through the element, 63.36 million joules of energy is used up during a period of 5 hours. This is also 1.76 kilowatt-hours.
110V times 3.2A equals 352 watts (joules per second).
352 watts times 3600 seconds per hour times 5 hours equals 63,360,000 joules.

∙ 14y agopower in watts = volts times amps
watts = 110* 3.2
=352 watts
for 5 hours = 352*5 watt-hours
=1760 watt hours = 1.76 kilowatt hours

Which electric element should be used so as to open the closed electric circuit?
A switch, circuit breaker, fuse, or switching transistor can do that.
How do you connect a voltmeter in parallel circuit?
A voltmeter is used to measure potential difference across two points in an electrical circuit . The voltmeter is connected in parallel across the circuit element (resistance ) so that its inclusion in the circuit has negligible effect on total resistance and current flowing in yhe circuit A voltmeter has high resistance,if connected in series it will increase of circuit and reduce the current in the circuit
Why are there fuses in plugs?
They protect the rest of the circuit when the current goes to high, usually, because of a short circuitshort circuit means a very low resistance is connecting the source terminalsthen according to ohm's law,Current = Voltage / ResistanceI = V/Ras R -> 0I -> Infinityassuming a fuse of 10A, when a short circuit occur, the current starts getting highonce it passes the 10A limit of the fuse, the circuit gets disconnected from the sourceA Fuse is an electrical element used in electrical circuits to give protection to the systems against high current flow.It prevents the hazardious conditions as a safety device.
Why does amperage stay the same in a circuit?
Amperes represents a flow of charge (coulombs) in a circuit in a period of time (seconds). In order to have that flow, you have to have conductance, which is the inverse of resistance. Since the conductance of two circuits not connected to each other is zero (infinite resistance, neglecting leakage) there can be no current flow between disjoint circuits. A node is a junction between two elements in a circuit, such as the connection between a resistor and a light bulb. If you consider that the only circuit between those two elements contains that node, and that leakage is inconsequential in comparision to the conductance of the circuit, then you have to note that the current entering the node must be the same as the current leaving the node. In fact, this is Kirchoff's Current Law: The sum of the currents entering a node must equal the sum of the currents leaving a node. (Usually, we think of current entering to be one sign (+) and current leaving to be the other sign (-), so the sum of all currents relative to the node is zero.) Expand this thinking little by little to encompass the elements in the circuit. Again, there is no path for current to flow other than through the elements of the circuit. This means that the current in every part of the circuit is the same. Keep in mind that this applies only to series circuits. In a parallel circuit, current can branch out between two elements connected to a node supplied by another element. In that case, the current in each branch will be different, depending on the resistance and voltage of that path. Circuit analysis is simply the consolidation of a complex circuit into a simple circuit by repeated application of various conversions, such as Norton and Thevanin equivalents, with the ultimate goal of knowing the voltage, current, and resistance for each element.
Is the heating element on a stove a chemical reaction?
No. It is a physical process cause be passing an electric current through a wire.
What is the name of a series circuit?
An electric circuit connected so that current passes through each circuit element in turn without branching.
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 is the difference in parallel circuit and series circuit?
In a series type circuit, the electric current passes through each element of the circuit (light bulb or whatever) in sequence; it does not reach any element until it has first passed through all the earlier elements. In a parallel type circuit, every element of the circuit receives its electric current independently. A separate wire connects each element to the source of the current rather than to the previous element of the circuit.
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 happens to voltages and currents when there are passive elements connected in series and in parallel?
In a series circuit the current flow in each element is equal but voltage across the each element is differ. In a parallel circuit the voltage across the each element is equal but current flow in each element is differ.
What electric element should be used so as to open the closed electric circuit?
which electric element should be used so as to open the closed electric circuit
What is the iffrence between a series circuit and parallel circuit?
Series circuit: elements are connected one after the other; the current (the electrons, or other charge carriers) has to pass through each of the elements in turn. Parallel circuit: elements are connected in such a way that part of the current will pass through one circuit element, part through the other.
Why ammemeter is attached in series in a circuit?
as the current in a series circuit remains the same so it does not cause any difference if an extra element is connected in between the various elements so an ammeter is always connected in series.
Is the potential difference across an electric circuit with no element drawing current from it the same at every pt?
there should not be any diff.because
Fuse should be connected to a circuit by parallel?
Fuse is a circuit element which disconnects the electrical current from the mains"supply" feeding the load when a condition of fault "short circuit " occurs. one behaviour of electric current that it flows undivided in circuit elements connected in series and is divided when flows in circuit elements connected in parallel. so in order to protect a circuit fuse MUST be connected in series to cut/disconnect the faulty current in a safe/short time. if u connect a fuse in parallel to a component then u will be shorting that component and the component will not function ;because the fuse is a thin wire with a negligible resistance and electrical current flows in the most easy "less resistive" component. besides a short circuit will happen immediatly because u connectthe supply to the neutral! hope that helps.
Why power does not remains same in series circuit?
In a series circuit, the current through each element is the same current. Because the total current must flow through every element. In a parallel circuit, the voltage across each element is the same voltage. Because every element is connected individually across the power supply.
What is a passive element in a circuit?
A passive element is an element of the electrical circuit that does not create power, like a capacitor, an inductance, a resistor or a memristor.
