How do you show resistance is proportional to L squared?
Okay. Resistance by ohms law is given by R = V/I But Power P = V * I Dividing R/P = 1/ I 2 Or R = P / I squared For a constant power, resistance is inversely proportional to I squared and not simply proportional to.
If power is constant increasing the voltage will increase or decrease current?
Decrease, because W = I (current) x V (voltage), if one increases, the other decreases in proportion to the increase of the other. Ohm's Law states current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
Is Power required to drive a centrifugal pump is directly proportional to diameter of the impellor?
yes....power is directly proportional to cube of dia.
Why During transmission of power it is transformed as high voltage rather than high current how is this possible as current and voltage are directly proportional?
Voltage and current are actually inversely proportional to one another. The formula P=IV is what you need to look at here, where P is Power, V is voltage, and I is current. Rearranging the equation you will see that V = P/I. You can see that if you increase voltage, while holding power constant, current is reduced. Now, to your question. The losses on a transmission line are proportional to the current flowing on the line, so transmitting at high voltage (and hence low current) is beneficial as it reduces the amount of power that is lost due to resistance in the line itself.
How does electric resistance relate to energy transformation?
Power in a circuit is inversely proportional to the resistance, all other things being equal. Voltage equals amperes time resistances, so amperes equals voltage divided by resistance. Watts equals voltage times amperes, so watts equals voltage squared divided by resistance.
Is power directly proportional to resistance?
No, power is not directly proportional to resistance. The power dissipated in a circuit is given by P = I^2 * R, where I is the current flowing through the circuit and R is the resistance. This means that power is proportional to the square of the current but linearly proportional to resistance.
How do you show resistance is proportional to L squared?
Okay. Resistance by ohms law is given by R = V/I But Power P = V * I Dividing R/P = 1/ I 2 Or R = P / I squared For a constant power, resistance is inversely proportional to I squared and not simply proportional to.
What is the Resistance for 25Watt bulb?
Knowing P=VI and R=V/I we derive that P=VxV/R i.e. resistance is inversely proportional to power. Resistance for a higher power is lower.
Why you select high resistance of heating element?
Because Heat is Directly Proportional to Resistance Of ElementAnswerPower is inversely, not directly, proportional to the resistance of a heating element.So, the higher the resistance, the lower the heating effect. For example, a 'high-wattage' lamp has a lower resistance than a 'low-wattage' lamp.This is because power is equal to the voltage squared divided by resistance; so, the lower the resistance, the more powerful (and, therefore, the hotter) the heating element.
Describe the relation between the size of your source and electric current?
The current drawn from a power source is directly proportional to the voltage of thesource, and inversely proportional to the resistance of the circuit between its terminals.There is no relationship between the current and the physical size of the source.
What is the equation or the formula getting power?
P(watt)=energy/time. Where power in measure in watt directly proportional to energy(work) and inversely proportional to time in seconds. 1W = .001kW
Instant conclusion for ohms law?
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor. It is represented by the formula I = V/R, where I is current, V is voltage, and R is resistance.
What is hydraulic horsepower?
A hydraulic variable that describes the power provided by a hydraulic system. HHP is directly proportional to flow rate and pressure and inversely proportional to the efficiency of a system
What is the relation between the velocity of a moving body and the resistance?
The velocity of a moving body is inversely proportional to the resistance it faces. This means that as the resistance increases, the velocity of the body decreases, and vice versa. More resistance leads to slower movement, while less resistance allows for faster movement.
If power is constant increasing the voltage will increase or decrease current?
Decrease, because W = I (current) x V (voltage), if one increases, the other decreases in proportion to the increase of the other. Ohm's Law states current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
What is the Relation between power factor and slip?
inversely proportional relationship
How does viscosity affect peripheral resistance?
If you increase the total peripheral resistance then the arterial blood pressure will increase.
