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 is good shelter for lightning?
A closed vehicle like a closed car is a good shelter for lightning. But we should never take shelter under a tree or an electric pole.
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.
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.
On an 50A circuit should you be able to turn all of three of your electric heaters on at the same time without tripping the main breaker?
Check the amp rating of the heater and do the math. Electric heaters pull A LOT of current, so I'm guessing you'd be near the 50amp max.
What 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?
there should not be any diff.because
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.
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.
Why do you need a circuit to make a light bulb work?
To get an open circuit to work and light a light bulb, turn the switch on. Or hardwire it to power up the lamp. If the battey or other power source is good, and so is the lamp, make sure all the connections are good and that the conductor (wire) isn't broken. With all the components in good shape and properly connected, the light should be glowing.
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
