Why is it not advisable to handle electrical circuit with wet hand?
Water is a good conductor of electricity. Should your hands be wet while working with a live electric circuit, the odds are increased that you will accidentally complete a connection and give yourself an electric shock.
What properties are needed for the heating element of an electric iron?
The heating element of an electric iron needs to have high electrical resistance, good heat conductivity, and resistance to oxidation. Additionally, it should be durable and able to reach and maintain high temperatures to effectively iron clothes.
Why would water not cause an electric circuit to trip?
Water in itself is not conductive enough to cause an electric circuit to trip. However, if water contains impurities or minerals that make it conductive, it could potentially cause a circuit to trip. Additionally, if water bridges two points of a circuit and completes a path for electricity to flow, it could cause a trip. It is important to note that water should be kept away from electrical circuits to ensure safety and prevent any potential damage.
Can you hook up a 240V circuit in series to a dryer and electric range?
The short answer is no. First off I assume you mean "can you have a dryer and an electric range on the same circuit?" (If they were actually wired in series, then you couldn't use your range if the dryer was off) In theory you could have them on the same circuit you just need to make sure that the wiring and the circuit they are on can handle the number of amps the two of them could draw together. If your breaker isn't big enough, it kill the power to the range while you are cooking dinner. If the wiring can't handle the load, then there is a fire risk. A dryer is usually on a 30amp circuit and a range is usually on a 50amp circuit, so to have them together would require an 80amp circuit, which will be difficult to find a breaker and wiring for.
What size wire and circuit breaker is needed for an electric oven 4 wires with rated load of 34.9 amps 220v that is about 100 foot run from the electrical panel?
That would be a 40 amp 220v circuit. Circuit breaker is 40 amps and wire is 8 awg. Should use solid copper wire. Follow oven installation instructions.
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
Is the potential difference across an electric circuit with no element drawing current from it the same at every pt?
Yes, in a circuit with no current draw, the potential difference is the same at every point in the circuit. This is due to the conservation of energy principle in electric circuits.
What are the characteristics of a simple circuit?
A simple circuit consists of a source of electro motive force ( EMF or voltage V ) This could be a battery,dynamo or solar cell. The circuit should do something, like light a lamp. For the lamp to glow there must be a flow of electrons called an electric current measure in Amperes (I). For the current to flow the circuit must form a closed loop, like a daisy chain. A switch is a device that breaks this loop and controls the state of the circuit. Closed circuit, switch closed, = lamp on Open circuit, switch not closed = lamp off
Classrooms should not have closed circuit cameras?
Of course they should. You are not doing anything in there you should not be doing, are you?
How does a switch control an electric device?
A switch basically represents a gap in the electric circuit. Electric current can pass through a circuit only if it is complete. An incomplete circuit can never pass a current through it. When the switch is in the 'off' position, the circuit has a break (gap) in it. When you put the switch in 'on' position, the circuit wire join and the circuit gets completed.
Should you connect both ends of a battery in a circuit?
Yes, both ends of a battery should be connected in a circuit to create a continuous flow of electric current. When one end of the battery is connected to one terminal of a component and the other end to the other terminal, a closed circuit is formed, allowing electricity to flow and power the device.
How should an ammeter be placed in a circuit?
An ammeter should be placed in series, between the element you want to know the current of and the node the element was attached to before.
What is the thyristor firing circuit?
The thyristor is basically used a switch in an AC circuit to control the amount of power fed to the load. To turn on this switch an "electric" pulse should be applied to the Gate terminal of the Thyristor. A circuit which supplies the "electric" pulse is called the firing circuit.
Using a cathode ray oscilloscope how do you measure the current in an electric circuit?
Cathode ray oscilloscope(CRO) is a device used to see the voltage across a particular element of your circuit and the wave form can also be seen on CRO. But you actually cannot measure the current using CRO as it is meant to give the voltage levels across any element in eletrically enegized circuit. however Digital Multimeter can do this job. But while using DMM to measure current one thing should be kept in mind that your circuit should be linear so that if you break the circuit to find current in series the current could not change in circuit.
Why is one bulb set up along a parallel circuit actually a series circuit?
In a series circuit, if you open a bulb, current loop will be broken. So, current cannot travel all the wayback, hence no output. But in a parallel circuit, current will be only shared with parallel circuit, but the loop remains closed even if you remove the bulb. So, no change occurs.
Why start button is Normally open?
Under normal conditions, the stop button should not be interrupting the circuit, so the circuit must be closed. When the stop button is used, it should open the circuit. it is a N.C. switch because this follows its' purpose.
What prevents you from receiving an electric shock?
Not touching a live conductive part of a circuit is a great way to prevent you from receiving an electrical shock! Along with this the circuit breaker should trip if there is a fault on the circuit, or a GFCI if there is no ground in the circuit
