What happens to the current of the wire when the length increases?
resistance is directly proportional to wire length and inversely proportional to wire cross-sectional area. In other words, If the wire length is doubled, the resistance is doubled too. If the wire diameter is doubled, the resistance will reduce to 1/4 of the original resistance.
Does the impedance of an RL series circuit varies inversely with the frequency?
The simple answer is no. The impedance of an R-Lcircuit is the vector sum of the circuit's resistance and its inductive reactance. Resistance is determined by the length, cross-sectional area, and resistivity of the conductor (although its 'a.c. resistance' is proportional to the frequency squared), whereas the inductive reactance is directly proportional to the frequency of the supply.
What three primary factors influence electrical resistance of circuit?
The resistance of any material is affected by its length, cross-sectional area, and resistivity. As resistivity varies with temperature, resistance is indirectly affected by temperature.Specifically, resistance is directly proportional to length and inversely proportional to cross-sectional area, and resistivity is the constant of proportionality.These factors apply to the conductors and all the components of your 'circuit' -including any insulation.
When the length is increased 2 times the value for resistivity will be?
The value for resistivity will remain unchanged (provided temperature remains constant). Resistivity is a property of the material. The resistance, however, will double. Remember that resistance is directly proportianal to the length of the conductor and inversely proportional to the cross-sectional area of the conductor.
State and explain ohms law?
Ohm's Law has nothing whatsoever to do with the factors that determine the resistance of a conductor.The resistance of a conductor is directly-proportional to the resistivity of the conducting material and to its length, and inversely-proportional to its cross-sectional area.
How are current and resistance related are they directly proprtional or inversely proportional?
inversely proportional
Do Power is directly proportional to resistance or inversely proportional to resistance?
It is both proportional and inversely propertional to resistance however I am not exactly sure why which is why I am searching Google ATM for answers.
Is the resistance of the wire directly or inversely proportional to the cross-sectional area of the wire?
The resistance of a wire is inversely proportional to the cross-sectional area of the wire. This means that as the cross-sectional area of the wire increases, the resistance decreases, and vice versa.
Which variable is inversely proportional to the resistance?
Inversely proportional to resistance is the current (I) in a circuit, as per Ohm's law: V = I * R, where V is voltage, I is current, and R is resistance. When resistance increases, current decreases, and vice versa.
What is directly and inversely proportional relationship?
Directly proportional relationship is F=ma, F is directly proportional to a. Inversely proportional relationship is v=r/t, v is inversely proportional to t.
Is voltage directly or inversely proportional?
Voltage is directly proportional to current, meaning that as voltage increases, current also increases and vice versa, as per Ohm's Law. However, voltage is inversely proportional to resistance, meaning that as voltage increases, resistance decreases and vice versa.
How does resistance affects electric current?
Ohm's law states that the current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance of a circuit.
Do resistors lower volts or amps?
Current is directly proportional to the applied emf (voltage) and inversely proportional to the resistance of the circuit.
What happens to voltage and resistance when increasing and decreasing is taking place?
As Ohm's law states; Current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
Is resistance inversely or directly proportional to temperature?
In most materials, resistance is directly proportional to temperature. This means that as temperature increases, resistance also increases. This relationship is described by the temperature coefficient of resistance, which varies for different materials.
Are speed and distance directly proportional or inversely proportional?
Directly proportional. Greater speed - greater distance.
Is potential difference directly or inversely proportional to resistance?
Potential difference is directly proportional to resistance according to Ohm's Law. This means that as resistance increases, the potential difference across a component also increases, assuming the current remains constant.
