What is the value of 1- cos x when x is small?
1 - cos x as x approaches 0. what is the cos of 0? It is 1. So as x approaches 0 cos x approaches 1. 1 - 1 = 0 So as it gets very small the solutions gets smaller.
Are there numbers bigger than infiniti?
Because infinity is not a number, this question is incorrect. You may think of infinity as something that has no bounds and gets larger and larger.
When you sell a call option who gets the dividend?
Dividends don't play into call options. If you sell a covered call and it expires worthless, you'll receive any dividends from the stock because you still own the stock. If it's exercised, the new owner receives them because the stock is hers now. The money that changes hands when you sell a call is the "premium," and the person who sells the call gets that.
How do you find the vertical asymptote for the logarithmic function f of x equals log x?
The only way I ever learned to find it was to think about it. The function f(x) = log(x) only exists of 'x' is positive. As 'x' gets smaller and smaller, the function asymptotically approaches the y-axis.
Do annuity rates remain steady or are they variable?
This actually depends on the annuity. A "fixed" annuity always gets you the same rate, while the rate of a "variable" annuity is indexed to some other rate, usually the federal prime rate. Rates are variable over the long term. It is possible to lock a steady rate in but it costs more to do so.
What happens to the current when the circuit gets cold?
When a circuit gets cold, the electrical resistance of the components may increase. This increased resistance can lead to a decrease in current flow through the circuit as Ohm's Law states that current is inversely proportional to resistance. Additionally, some materials, like semiconductors, may exhibit changes in conductivity with temperature, affecting current flow as well.
When one resistance or load in a series circuit gets defective the circuit becomes?
The circuit will become an open circuit.
What effect does adding devices have on the resistance of the series circuit?
Many circuits have safety devices such as fuse. A fuse contains a substance that melts if it gets hot. if a short circuit happens, the heat causes the fuse to melt. The circuit is broken. because the current stops ,no damage is done.
Why does resistance increase in a series circuit?
In a series circuit, the total resistance increases because the individual resistances add up. As the current flows through each component in succession, the resistance offered by each component adds to the total resistance. This leads to an overall increase in resistance in a series circuit.

What happens when the field circuit gets opened while the dc machine is running?
the f
What is infinity resistance?
That's an "open circuit". No current flows no matter how high the voltage gets. It doesn't exist in nature.
Why does the resistance in a series circuit which includes a light bulb increase when the bulb lights up?
When the light bulb in a series circuit lights up, its filament gets hotter and its resistance increases. This increase in resistance causes the overall resistance in the circuit to rise, as the resistance of the light bulb is in series with the rest of the components.
What happens to a thermistor as it gets colder?
As a thermistor gets colder, its resistance increases. This is because the material in the thermistor contracts, reducing the number of charge carriers available for conduction, hence increasing resistance.
What happens to light bulb in a circuit when the wire gets skinnier?
it either blows up or worn out
What happen when ammeter connected in parallel?
an ideal ammeter has zero or negligible resistance when this is connected in series no effective resistance would be added in the circuit so that the value of curret that we get is exactly of the circuit only. but when the ammeter is connected in parllel as it has zero resistance , the resistor to which it is connected in parllel gets shorted and due to his the effective resistance of the circuit is changed and so the effective current ... due to this the w=value measured by the ammeter would be different (incresed due to dec. in effective resistance)
What gets used up in an electric circuit current or energy?
One of Kierchieff's laws tell us that the more wattage (energy) consumed by an electrical device in a circuit, the larger the voltage difference that exists across the device and the greater the current flowing through it. The energy consumed is directly proportional to the Impedance of the electrical device but is more importantly proportional to the square of the current. WATTS=VOLTS X AMPERES= RESISTANCE (IMPEDANCE) X AMPERES X AMPERES A Circuit with Current but without resistance would exhibit no energy at all.
