No.
AnswerPresumably, you mean 'specific gravity' or, as it is known these days, 'relative density'? If so, the relative density of a lead-acid cell or battery is, indeed, a guide to that battery's state of charge -that's why we use a hydrometer to check the condition of a lead-acid battery. However, it would be wrong to say that the relative density of a lead-acid battery 'effects' the voltage -it merely is a guide to the state of charge. (Actually, it's the state of a battery's charge that affects its relative density.)

A 12 volts power supply is connected across two resistors R1 120 ohms and R2 470 ohms in series Calculate the potential difference across each when the negative terminal of supply is earthed explain?
Earthing of the negative terminal is a common practice and will not affect the potential across the resistors in the circuit. Calculating this is simple Ohm's Law. For a series circuit: R(total) = R1 + R2 + R3....... Rn In this case: Rt = 120 + 470 = 590 ohms Per ohms law E = I x R. We need to find the current flowing throught the circuit so: I = E/R = 12 / 590 = .0203 amps or 20.3 milliamps The potential across an individual resistor is calculated again by E = I x R So for R1 (120 ohms): E1 = I x R1 = .0203 x 120 = 2.44 V So for R2 (470 ohms): E2 = I x R2 = .0203 x 470 = 9.54 V For a check E = E1 + E2 = 2.44 + 9.54 = 11.98 The .02 difference is due to the use of significant figures.Another AnswerEarthing the negative terminal will have no affect on the potential DIFFERENCE across each resistor. 'Potential' exists at a single point. 'Potential difference' exists between two points.
What is meant by creeping in energy meter?
Hii creep is a phenomenon that can adversely affect accuracy, that occurs when the meter disc rotates continuously with potential applied and the load terminals open circuited. A test for error due to creep is called a creep test.
What is the difference between AGND and DGND?
AGND means Analog ground & DGND means Digital ground. Due to fast switching of digital signals it is possible for noise generation which affect nearby analog signals.(If common gnd used for both analog & digital). If separate gnd used for both the signals.Noise will not affect the signals.
What is the difference between amplitude shift keying and AM modulation system?
Major disadvantage is that telephone lines are very susceptible to variations in transmission quality that can affect amplitude Ann
What are the factors that affect the bias stability of a transistor?
temperature
Does acidity affect voltage?
Acidity is the potential for Hydrogen ions in a solution Voltage is the electrical potential difference. These have nothing to do with each other per se. They can be involved in a battery or electrochemical reaction....
What factors affect the amount of gravitational potential energy?
Mass, gravity, height.
What factors affect water potential?
solute concentration and pressure
What will affect the amount of gravitational potential energy?
The mass, height and the force of gravity at the location.
What are he factor that affect potential energy?
This can be deduced quite simply from the formula for potential energy: PE = mgh (potential energy = mass x gravity x height)
What will affect the electrolysis of molten copper chloride?
temperature and potential difference of electrodes.
How does mass affect gravitational potential energy?
the formula for gravitational potential energy if mgh(mass X gravity X height). gravity is always 9.81m/s2. assume height is constant, more mass means more gravitational potential energy and vice versa
Which factors affect water potential in living cells?
Some factors which influence water potential include gravity, pressure, and solute concentration. Adding solute lowers the water potential. An increase of pressure will increase the water potential.
How do the mass and height of object affect the gravitational potential energy?
potential energy is mass times height times gravity acceleration; so for example if you double the height or double the mass you double the potential energy
How does the potential difference in the resistor change as the current through it changes?
The potential difference accross the resistor changes mainly due to gradual increase accumulation of electrons in the lower potential region which will in turn affect the potential gradient as the current flows through the resistor
How does the increase or decrease of potential difference affect the flow of the electric current?
Increase or decrease in potential results in the change in direction of the flow of electric current.
How does an objects mass affect its potential enegry?
There are different sorts of potential energy but the most common in physics is gravitational potential energy. An object of mass m has a potential energy of mgh where g is gravity (9.81 in metric units) and h is the height above ground.
