What does the U represent in ohms law?
Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points, and inversely proportional to the resistance between them.AnswerTo answer the question, U, is a symbol for potential difference. Alternative symbols are E and V. Originally, I believe, 'U' was a German symbol, but it has since been adopted throughout the EU..
What happens to voltage when resistance increases?
Ohm's law states that "The current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance in the circuit." <<>> if resistor exists, resistance decreases according to ohm's law, current is directly proportional to voltage and current is inversely proportional to resistance it means as current increases, voltage increases. resistance increases, current decreases so as voltage if there is no resistor, there should be no resistance except internal resistance of voltmeter and ammeter
Why gain increases in low frequency region in BJT?
Because Beta (current gain) in a transistor is inversely proportional to frequency. Hence it increases as frequency decreases. Also the ac voltage gain is directly proportional to Beta.
How do the partial current behave in relation to the corresponding resistance value for parallel circuiting of resistors?
The ratio of current flow through individual branches of a parallel circuit is inversely proportional to the ratio of resistance of each branch.
Why current lag and potemtial lead in an inductor.?
because of flux produced in coil of inducterAnswerThe potential difference (not 'potential') induced into a pure inductive component is proportional to the rate of change of current. The greatest rate of change of current occurs when the current waveform passes through zero (i.e. is at its steepest angle). So the voltage is maximum when the current is passing through zero -which means that the current is lagging the voltage by 90 degrees.
How does resistance after current?
Assuming you are asking "How does resistance altercurrent?", then the answer is that, for a given value of potential difference, the current is inversely-proportional to the resistance. E.g. doubling the resistance will reduce the current by half.
Current in a circuit is inversely proportional to?
In a circuit , current is inversely proportional to the resistance.
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.
Current is inversely proportional to resistance?
Current is inversely proportional to resistance, this comes from the ohms law. V=IR If we keep the voltage as constant then Current will be inversely proportional to resistance
What is the relationship between the current flowing through a wire and the potential difference across it?
The relationship between the current flowing through a wire and the potential difference across it is described by Ohm's Law. Ohm's Law states that the current (I) flowing through a wire is directly proportional to the potential difference (V) across it, and inversely proportional to the resistance (R) of the wire. Mathematically, this relationship is represented as V I R.
How are current and resistance related are they directly proprtional or inversely proportional?
inversely proportional
What are the factors of ohms law?
Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points, and inversely proportional to the resistance between them
How does current increase when potential difference increase?
Current increases with an increase in potential difference due to Ohm's Law, which states that current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R): (I = \frac{V}{R}). As the potential difference across a conductor rises, more voltage pushes charge carriers through the circuit, resulting in a higher current, assuming resistance remains constant. This relationship is fundamental in understanding how electrical circuits operate.
List two factors that affect the amount of electric current in a wire?
according to ohm's law V = IR or I = V/R 1. so current is directly proportional to potential difference across the wire 2. and it is inversely proportional to resistance of wire.
The statement that current is directly proportional to voltage and inversely proportional to resistance is known as whose law?
The statement current is directly proportional to voltage and inversely proportional to resistance is known as Ohm's Law.
What is ohm low?
v=ir Ohm's law states that , in a dc circuit the current is directly proportional to the applied voltage and inversely proportional to the resistance at a constant temperature. It has the formula V=IR where I is the current and R is the resistance.
What is the relationship between electric potential and a wire in an electrical circuit?
The electric potential in a wire in an electrical circuit is the amount of electric potential energy per unit charge. As the wire carries current, the electric potential decreases along the wire due to the resistance of the wire. This relationship is described by Ohm's Law, which states that the electric potential difference across a wire is directly proportional to the current flowing through it and inversely proportional to the resistance of the wire.
