What are factors that affect resistance of electricity?
Temperature, thickness, length and type of wire.
How can electric current be changed in Omh's Law?
Ohm's Law: V = IR Solving for current: I = V/R To affect the current, you can either change the voltage (more voltage --> more current), or the resistance (more resistance --> less current).
Is there a direct or inverse proportion between voltage and resistance?
voltage is directly proportional to resistance, and the current is inversely proportional to resistance. According to Ohm's Law, current is directly proportional to voltage.
What is the relationship of current to resistance if voltage is constant?
Ohm's Law states: V = IR, where V is voltage, I is current and R is resistance. If the voltage is constant, then current is inversely proportional to the resistance.
What is the relationship between the voltage and the current when the resistance is kept constant?
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
Reducing voltage in a circuit does not affect resistance?
Reducing voltage in a circuit does not directly affect resistance. It affects current. Resistance is an independent variable.Ohm's law: voltage equals current times resistance.However, reducing voltage and/or current does reduce power, which reduces temperature, which can change resistance because resistance is usually affected to some degree by temperature.
Resistance of a copper conductor will decrease with an increase of applied voltage?
Resistance is affected by the length, cross-sectional area, and resistivity of the conductor. The resistivity, in turn, is affected by temperature. So only by changing one of these four factors will the resistance of a conductor change. Changing voltage will have no affect upon the conductor's resistance.
How does the changing the battery voltage affect the current?
If voltage varies then current varies with constant resistance.
What would affect the brightness of a lamp?
Voltage applied (voltage at source, resistance of wire and conections etc), ground resistance, designed brightness of element in comparison to the applied voltage
What causes resistance to increase or decrease?
Voltage, if voltage is increased resistance in the circuit increasesAnswerResistance is determined by the length, cross-sectional area, and resistivity of a conductor. Resistivity is, in turn, affected by temperature -so temperature indirectly affects resistance.These are the only factors that affect resistance. Voltage and current have no direct effect whatsoever on resistance. Current can affect resistance indirectly if it causes the conductor's temperature to increase.For AC circuits, 'skin effect', due to frequency, causes the current to flow towards the surface of a conductor which acts to reduce the effective cross-sectional area of that conductor. So, frequency can also indirectly affect resistance.
Which of the following factors does not affect the voltage produced in a voltaic cell?
Voltage is not stoichiometric, so increasing the number of moles of a substance will not affect its voltage.
How does loading effect affect flow of current?
Ohm's Law says that Voltage = Current x Resistance (Load). Therefore Current = Voltage / Resistance and as resistance decreases current increases and as resistance increases current decreases.
Do the resistance depend on temperature and bias voltage?
Yes it depends on temperature and bias voltageAnswerNo. Although temperature may affect resistance indirectly (if actually affects resistivity, rather than resistance), a material will have resistance whether there is a voltage present or not.
What are three related electrical factors did George Ohm investigate?
the answer is current, voltage, and resistance
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is a relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
