What is a sign of a short circuit?
A common sign of a short circuit is a blown fuse or a tripped breaker. Also visually seeing a burned wire and of course the smell of burned insulation all give an indication of a short circuit.
What is the current through the 150 ohm resistor?
It depends on the voltage applied across it. But the maximum current is limited by the power-rating of the resistor (power divided by the square of the voltage).
Why maximum power is transferred when impedance of source and load is same?
Note that this is about maximum power transfer, NOT about maximum efficiency.The source resistance is assumed to be constant; the load resistant variable. If you know about calculus, you can derive the maximum power transferred by writing an expression for the power as a function of the variable load. You need no advanced calculus for this - just derivatives, which are used to get the maximum or minimum of a function (as well as high school algebra, of course). You can find the derivation (for the simplified case of a purely resistive circuit) in the Wikipedia article on "Maximum power transfer theorem", as well as a link to the more general case.
A device or circuit that provides power to the rest of the circuit or system is called what?
A device or circuit that provides power to the rest of the circuit or system is called a power supply,
Where circuit breaker are used?
Circuit breakers do not use anything, they are a controlling device. They can automatically open the circuit if the current exceeds the current rating and you can manually disconnect the power from the circuit.
What is a signal circuit?
What is a power limited circuit
What is signal circuit?
What is a power limited circuit
In which circuit will the light bulb be the brightest?
the circuit which has the maximum power output
What is the condition of maximium power transfer of circuit?
Maximum power transfer happens in a circuit when the resistance of the circuit equals the reactance. Impedance Z = R + jX. At R=X, maximum power transfer happens.
How many smoke alarms can i put on an existing lighting circuit?
As a general rule, a lighting circuit should be lamped only for a maximum of 80 percent of the rated branch protection. So if it is a 15-amp circuit, you could put in fixtures for up to 12 amps, including any smoke alarms (assuming code allows anything other than lighting on that branch). Each smoke detector has a power consumption figure, if not also a required amperage. Add them all up and add that to the existing lighting to see if it is still under the 80 percent maximum design load.
How maximum output power obtained?
when all the resistance removed from the circuit
Maximum no of power sockets allowed in one circuit?
10 nos
Is there a battery pack that a wall plug can plug into to have power?
Yes, but the power is limited. Normally used only for lighting when main power is out
When a source is delivering maximum power to load the efficiency of the circuit is always?
50%
What is maximum power of a 59ma power and 8.2kohm resistor circuit?
P=I2R=(59mA)2(8.2kohms)= 28.5443W
What is Doubling Effect in power system?
It is define as twice the maximum symetrical short circuit current.
Why would you have power to your tail lights when switch is of?
it shows that somewhere on the tail lighting circuit there is some kind of a short circuit,one can test using a multimeter to find the probklem..
