2 resistors unequal value are in parallel. Would the power dissipated by the resistor with larger ohmic value be greater than the power dissipated by the resistor of lesser value?

No, because the power dissipated in a resistor is proportional to the square of the current through the resistor but only directly proportional to the resistance of the resistor (I^2 * R) and the current through the lower value resistor will be higher than the current through the higher value resistor, the lower value resistor will usually dissipate more power.

Is it possible to increase wattage in a resistor?
No, it is not possible to increase wattage in a resistor.The resistor is designed with a specific wattage (power) rating, which is a function of its temperature coefficient and thermal transfer characteristics. Altering that would be more complex and costly than simply getting a resistor with a larger power rating.As a quick solution, use four identical resistors, two in series, and those two sets in parallel. The equivalent resistance would be the same, but the power rating, assuming you maintain adequate separation, would be four times greater. Parasitic inductance and capacitance would be slightly different but, that should not matter, depending on the application.
What will happens if zener diode and resistance are connected in parallel?
If diode is connected in series then current will flow only in one direction. ie. Current flow occurs only when diode is forward biased. ANSWER: It depends are the diodes are connected in series if they are back to back no current will flow if connected in the forward conduction mode then they will conduct.
What are the three great truths about circuitry?
1. The sum of the component voltage drops in a series circuit is equal to the voltage at the source.Vs=V1+V2+...+Vn (s=source, n=total number of voltage drops in the circuit)2. The greater the resistance imposed by a component, the greater the voltage drop across it.Larger resistor=larger voltage drops, Smaller resistor=smaller voltage drops3. In a series circuit, the percentage of resistance contributed by a component is equal to the percentage of voltage dropped by that component.
What is the Q factor in RLC circuit?
It is related to damping in the circuit using a resistor. Q is inversely proportional to the resistor(R). So if the value of resistance is high, there is a greater damping and the value of Q will be low. if resistance is low, there is small damping and Q will be high. when Q is high(low damping) the graph of voltage across resistor against frequency will be sharp at resonance and the bandwidth will be small when Q is low(high damping) thee graph will be less sharp as the bandwidth will be large. Go do some research on the graphs and the formula of Q factor to understand it better.
What you will do to measure voltage which is greater than voltage limit of the cathode ray oscilloscope?
change your resistance, its a little button, or if you are using an older oscilloscope, its a knob that will lower the sensitivity of the display. if it is something way higher than the oscilloscope can measure, you may have to run a resistor or transformer in the line.
How does electricity react to resistances in parallel and in series?
Resistances in series act just as if they were one single resistor. The value of the single resistor is the sum of the individual resistors connected in series ... Ra + Rb + Rc etc. When several resistors are in series, the effective total is greater than the biggest one. Resistance in parallel act just as if they were one single resistor. The reciprocal of the value of the single resistor is the sum of the reciprocals of the individual resistors connected in parallel ... Total effective resistance = 1 divided by (1/Ra + 1/Rb + 1/Rc + etc.) When several resistors are in parallel, the effective total is less than the smallest one. Once you figure out the effective value of the series- or parallel-combination of many resistors, you handle them as if they were one single resistor, and you can work with the voltage and current: Current through any resistance = (Voltage across it) divided by (its resistance).
What is the effect on the total resistance if increase in resistors in series?
That depends ... in a very interesting way ... on whether they are connected in series or in parallel. -- If the resistors are in series, then the total resistance increases when you add another resistor, and it's always greater than the biggest single one. -- If the resistors are in parallel, then the total resistance decreases when you add another resistor, and it's always less than the smallest single one.
To connect a pair of resistors so that their equivalent resistance is greater than the resistance of either one should you connect them in series or in parallel?
When many resistances are connected in series, the equivalent resistance is greater than the greatest single resistance. When many resistances are connected in parallel, the equivalent resistance is less than the smallest single resistance.
What is the function of a cement resistor?
A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).

What is the main difference in operation between diodes and resistors?
A diode is an electronic component which only allows the current to pass through it in one direction. This is useful in many aplications, such as preventing current to flow in the wrong direction in a circuit. A resistor is also an electronic component, but instead of preventing the current from moving in a certain direction the resistor creates an electrical resistance which will effect the current passing through it. The larger the resistance of the resistor, which is measured in Ohm, the greater the effect it will have on the current.
What a weak pull up resistor?
A: That refers to a resistor pull up that is not sufficient to do the job that is to pull up. It also means is greater in value that it should be
Is there more resistance in the series circuit or the parallel circuit?
Ohm's Law says! R=V/I Resistance is directly proportional to Voltage. In series circuit, due to adding the resistance, total voltage will be increased, due to increasing of total voltage, total resistance of the series also be increased.
Is potential difference directly or inversely proportional to resistance?
Potential Difference (V) across two resistors is directly proportional to the resistance (R) as greater the potential difference, greater is the resistance and vice versa.
Is it true that the higher a resistance value the higher the voltage drop?
Greater value resistor will absorb more voltage than smaller value. The more voltage absorb with same value current flow, the larger body mass resistor will require. Body size depends on type of resistor (material resistor is made of).
What is difference between neutral grounding reactor and neutral grounding resistor?
They both reduce earth fault levels by inserting impedance in the return path. A reactor is used when the earth fault level wanted is greater than about 25% of the phase fault current. This limit is due to over voltages experienced in arcing faults, the higher the reactor impedance the higher the potential overvoltage. With resistors lower fault levels are possible, but as the resistor has to dissipate all energy it will generally be more expensive and larger than a reactor.
