What would happen to the resistance if a soft iron core was energised with steady dc?
The resistance would remain the same because it is determined by the material and dimensions of the wire, not the presence of an energized soft iron core. The core would become magnetized and the magnetic field around the wire would change, but this would not directly affect the resistance of the wire.

How much resistance should be on a 5.0 kw heat strip?
Depends on the voltage. Wattage is Volts x Amps. Resistance (ohms) is Volts divided by Amps. So on a 120V circuit, it would draw 41.66 amps. To do that, it would need a resistance of 2.88 ohms. But on a 240V circuit, it would draw 20.83 amps. That would require a resistance of 11.52 ohms. Determine the circuit voltage, then use that to figure the amps, then use that result to calculate the resistance necessary.
What do you think would happen if you put a 3A fuse in a plug used for kettle?
I know what would happen. The three amp fuse would blow. Any device that is plugged into a receptacle with out having sufficient resistance to limit the current flow will dead short the circuit and cause the breaker that feeds the circuit to trip. In this case the fuse being of a lower rating that the feed breaker the fuse will blow without tripping the receptacle's feed breaker.
What would happen if all receptor proteins were removed from the membranes of a liver cell?
Nothing would happen at all.
What is the resistance of a 36watts ballast?
The resistance of a ballast can vary depending on its design and specific characteristics. To calculate the resistance of a 36-watt ballast, you would first need to know the voltage it operates at. Using Ohm's Law (R = V^2 / P), where R is resistance, V is voltage, and P is power, you can determine the resistance.
What would happen if you remove the vein from a leaf?
what would happen if we remove the vein from the leaf
What is self resistance?
Self resistance is exactly what it sounds like it would be. It is the resistance that you make happen on your own.
What would happen if you reduced the resistance in a circut?
current will increase
What would happen to circuit if there was no resistance?
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
Do the green transformer boxes ever stop working and when the electrical company closes for the day do they shut off the transformer boxes?
No. Transformers remain energised permanently and are only disconnected for maintenance. If the company were to shut off the transformer, then you would lose the electricity supply to your property. An energised transformer normally hums, which is usually an indication that it is energised, however you should ALWAYS assume that a transformer is energised and never interfere with it.
How is air resistance is force?
It requires a force to propel an object through air, because of the air resistance. Normally, if there were no air resistance and the object were being propelled on the level with no friction, a constant force would accelerate the object steadily. However, it would require a steady force to propel the object through air even without acceleration. And the faster it went the more resistance it would meet.
Why would amps reduce when voltage is raised?
This would only happen if resistance was increasing faster than the rise in voltage.
What is insulation resistance in capacitor?
ideally there will not be any resistance to the capacitor,so at this condition it should not not discharge the stored energy. but practically small resistance will be there in the capacitor so the energy stored by the capacitor will be discharged through resistance.
What will happen if a scientist makes a boat with the least resistance?
In that case you would have a boat that uses less fuel.
What will happen to the brightness of blub connected in series with a solenoid with a source of dc?
THE brightness would decrease as solenoid would have some resistance.
What would happen to current if the voltage is constant and the resistance is dounbled?
by the ohms law we can clearly say that the current is the ratio of voltage to the resistance.as the resistance is doubled the current should be halved.
If there are no air resistance what would happen to the hailstones?
Without air resistance, hailstones would fall faster and potentially reach higher speeds due to the absence of drag slowing them down. They would hit the ground with more force compared to in a situation with air resistance.
What would happen to the current in a simple circuit if a bulb with a higher resistance were used?
If a bulb with higher resistance is used in a simple circuit, the total resistance in the circuit would increase. According to Ohm's Law (V=IR), with an increase in resistance, the current in the circuit would decrease since the voltage supplied remains constant.
