What is the shape of the graph between volt and electric charge where Volt is the potential difference between the ends of an ohmic resisitor and electric charge is the current flowing through it?

-- If one axis of your graph represents the current flowing through the resistor,
then label it "Current", not "Electric charge". There's a big difference between
charge and current.
-- Ideally, the current through an ohmic resistor is a linear function of the voltage
across its ends, namely a direct proportion with the resistance being the constant
of proportionality.
-- Ideally, the graph is a straight line, with slope equal to the resistance in ohms,
and y-intercept of zero.
-- In reality, the resistor dissipates energy at the rate of (voltage) x (current) watts.
It must warm up as a result, and the change in its temperature always has some effect
on its ohmic resistance.

Why you get an electric shock if you touch live and neutral wire?
Because there is a potential difference between the live and neutral wires.
What is the definition of voltage?
Difference in potential between two points. Like the voltage of an energizer AA battery is 1.5 volts BETWEEN its terminals. If you place two AA batteries in a flashlight, the voltage of the series combination of AA batteries from one tip to the other is now 3 volts.
How can you measure electric potential and electric current?
Potential . . .Always measured as a potential difference between two points.The most practical way to do that is with a voltemeter connectedin parallel with any circuit between the two points.Electric current . . .The most practical way to measure current is with an ammeter connectedin series in the path of the current.
What is a difference in electric charge called?
The chemical gradient refers to the imbalance of substances across the membrane. The Electrical Gradient refers to the difference of charges between substances on different sides of the Membrane. The Electrochemical Gradient refers to the combination of the previous two gradients. The short answer is MEMBRANE POTENTIAL.
Difference in a charge between two electrodes in a cell causes a ----between electrodes?
Potential difference.
What is the difference between electrical potential energy and potential difference?
Electric potential is the electric potential energy per unit coulomb. So unit for electric potential is J/C and that of electric potential energy is simply J
What difference between electric potential energy and mechanical potential energy?
Dadsca
What is the difference between electrical potential and electromotive force?
electric potential is potential difference between two points in closed circuit. but electromotive force is potential difference in any open circuit.
What is the definition of potential defference?
The difference, measured in volts, in electric potential between two points.
What is volt of electricity?
Voltage is the measure of the electric potential difference between two points in an electric circuit. It is the amount of potential energy per unit charge available to move electrons from one point to another. Voltage is measured in units called volts, symbolized by the letter V.
Explain why an electric discharge occurs?
Because there is a potential difference between two objects.
What is electric potential in between twooppositely charged plates?
The electric potential difference is measured in volts. The amount of volts will depend on what kind of plates and the solution which the plates have been put in to.
Clearly distinguish between electric potential energy and electric potential?
Potential difference means the difference in the potentials at two specified points. If "potential" is mentioned without any such qualifier it usually means the potential difference between a point and the "earth" or "grounded terminal". The prefix "electric" is just a reminder we are talking electrically. But the same argument applies equally to gravitational potential.
What cause an electric current to move through a wire?
An electromotive force or potential difference between its ends.
Uses of voltmeter?
A voltmeter is used to measure the difference in electric potential ("voltage") between two points, usually but not necessarily in an electrical circuit..
What causes the flow of electric current?
Electromotive force (potential difference, voltage) between two points of a conductor.
Why you get an electric shock if you touch live and neutral wire?
Because there is a potential difference between the live and neutral wires.
