What is meant by the resistance of an electrical component?
Think of it like this: Friction causes you difficulty in pulling heavy objects on a carpet. This frictional force is similar to electrical resistance. It is one of two ways to define how easily electricity will travel through an electrical element.
What is a nonlinear electrical load?
It must mean a load that is not constant, or does not follow a straight line relation with some other parameter. For example air resistance- the drag on a vehicle increases as the square of the speed, so the load on the motor increases at a similar rate ( or at least that part of the motor load used to overcome air resistance)
Which of the material is used for the swamping resistance that is connected in series with the working coil of a voltmeter?
A swamping resistor is usually manufactured from the metal alloy manganin (trade name), or other alloy with similar resistance/temperature characteristics -i.e. practically zero temperature coefficient of resistance. In other words, its resistance will remain more-or-less constant over a wide range of temperature variation.
A circuit contains two devices that are connected in parallel if the resistance of one of these devices is 12 ohms and the resistance of the other device is 4 ohms the total resistance of the two devi?
The net effective resistance of the parallel devices is the reciprocal of (1/12 + 1/4). Hence 3 ohms.=============================================(Which actually looks strangely similar to the first answer above.Could it be just coincidence ? I wonder . . . )
What is the effect on total resistance of adding this third bulb?
If a fourth bulb were added in a similar way to the three existing bulbs, the resistance in the circuit would go up if the bulbs were series connected, and it would go down if the bulbs were parallel connected.
Resistance is measured in what?
Electrical resistance (and impedance) is measured in ohms(Ω).

Why is the efficiency of a transformer less than 100?
Assuming you're asking about an electrical transformer... Electricity meets resistance as it flows threw the transformer. Some of the flow of the energy is converted to heat due to the resistance and you get less electrical energy out than you put in. Think of electrical resistance as similar to friction between two objects, say rubbing your hands together quickly and generating heat.
Which electrical properties does Ohm's Law relate and how?
Ohm's Law states that the voltage across a load in a circuit is equal to the product of the resistance of the load and the current flowing through it.E = I * RE ==> voltageI ==> currentR ==> resistanceIf you compare an electrical circuit to your household plumbing, resistance is similar to a restriction or partial obstruction in the plumbing, like a partially open faucet, current is similar to the rate at which water flows through the plumbing or from the faucet, and voltage is comparable to the water pressure.
Why electrical resistivity of metals change with increasing laser shots?
it is similar to that of heating a metal heating a metal leads to increase in resistance thus both laser shot or heating are form of heat transfer that leads the atoms to higher energy states causing random movement of electrons vigorously which increases resistance

What is meant by the equivalent impedance of a parallel ac circuit?
This is similar to "equivalent resistance", but impedance is a more accurate concept in the case of AC.The equivalent resistance (or equivalent impedance) means that if you replace all the resistances under consideration with one equivalent resistance, the result on the circuit will be the same.This is similar to "equivalent resistance", but impedance is a more accurate concept in the case of AC.The equivalent resistance (or equivalent impedance) means that if you replace all the resistances under consideration with one equivalent resistance, the result on the circuit will be the same.This is similar to "equivalent resistance", but impedance is a more accurate concept in the case of AC.The equivalent resistance (or equivalent impedance) means that if you replace all the resistances under consideration with one equivalent resistance, the result on the circuit will be the same.This is similar to "equivalent resistance", but impedance is a more accurate concept in the case of AC.The equivalent resistance (or equivalent impedance) means that if you replace all the resistances under consideration with one equivalent resistance, the result on the circuit will be the same.
