What else can I help you with?
What happens with electric current when applying the same voltage the resistance of the circuit is reduced?
As the resistance is reduced across the same voltage, the current increases.
What does Ohm's law describe about the relationship between voltage, current, and resistance?
Ohm's law describes the relationship between voltage, current, and resistance in an electrical circuit. It states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor. This means that if the voltage increases, the current will also increase, but if the resistance increases, the current will decrease.
What else increases as energy carried by a current increases?
The amount of electric energy that is converted into thermal energy increases as the resistance of wire increases. As the resistance in the current increases, the current in the circuit decreases.
If the voltage impressed across a circuit is constant but the resistance increases by a factor of 7 By what factor does the current change?
A: 1/7
How does load current vary with the load resistance?
Their relationship is only dependent on the voltage lost across that resistor; voltage equals resistance times current, so increasing the current for a given voltage will require a decrease in the resistance, and vice versa.
What is ordinary fuse law?
Ohm's Law states that the current passing through a conductor between two points is directly proportional to the voltage across the two points. This means that as voltage increases, current increases, and as resistance increases, current decreases.
Does increasing the voltage across a resistor increase the electric current through the resistor?
Resistance is not affected by either voltage or current. It is determined only by the cross-sectional area, length, and resistivity of the material. As resistivity is affected by temperature, resistance is indirectly affected by temperature.In the so-called 'Ohm's Law' equation, resistance is a constant. So, if you increase voltage, the resistance remains constant, and the current would increase in proportional to the voltage.
What is the value of a resistor when current and voltage are both zero?
The value can be anything.As long as the resistance is not zero, if the voltage across the resistor is zero the current through the resistor will also be zero.The relevant equations is...Voltage = Resistance x CurrentIn the special case of superconductivity, the resistance is zero and you can have a current even if the voltage is zero.AnswerResistance is affected by the length of a material, its cross-sectional area, and its resistivity (which, in turn, is affected by temperature). The resistance of a resistor, therefore, is not affected by either voltage or current.
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.
What is the relationship between voltage and resistance in an electrical circuit?
In an electrical circuit, the relationship between voltage and resistance is described by Ohm's Law. This law states that the voltage across a circuit is directly proportional to the resistance in the circuit. In other words, as resistance increases, the voltage required to maintain the same current also increases. Conversely, if resistance decreases, the voltage required to maintain the same current decreases.
What is a IR drop across a resistance?
IR drop across a resistance is voltage. The letter I means current, and the letter R means resistance. Current times resistance, by Ohm's law is voltage.
Is there a direct or inverse proportion between voltage and resistance?
There is an inverse proportion between voltage and resistance according to Ohm's Law: V = IR, where V is voltage, I is current, and R is resistance. This means that as resistance increases, the voltage across the circuit decreases, and vice versa.
