What is an effective resistance?
the resistance to an alternating current, expressed as the ratio of the power dissipated to the square of the effective current.
What is the formula of effective resistance?
The effective resistance between vertices a and b (after connecting a voltage source between them) is defined as the potential difference between a and b per unit net current from a to b. In other words, Rab = va vb Iab . Once we fix the current from a to b to be Iab = 1, the effective resistance becomes Rab = va vb.
What is effective resistance class 10?
In a complex circuit consisting of two or more resistors, the effective resistance is the measure of the total resistance of all the resistor in the circuit.
What is the difference between more resistance and equivalent resistance?
More resistance means less current is flowing through the circuit. Equivalent resistance is a different way of indicating ‘total’ resistance, which we calculate differently for series and parallel circuits. In a series circuit, the different components are connected in a single, continuous loop.
What is the equivalent resistance in a parallel circuit?
Thus, the presence of two 4 resistors in parallel will be equal to one 2 resistor in the circuit. This is the concept of equivalent resistance in a parallel circuit. If all components are connected in series, the circuit is referred to as a series circuit.
What is the effective resistance of a circuit?
The effective resistance of a complex Network of two or more resistors in some series or parallel arrangement has an effective resistance between any two points. In the simple case that could also be equal to the Thévenin equivalent. In an AC circuit it could be the real parts of the impedance.
What is the difference between effective resistance andresistance?
Resistance usually refers to the resistance of 1 element. For example, if there are 2 resistors in series, one with 1 Ω and the other with 2 Ω resistance, then the resistance of the first resistor is 1 Ω. However, if you had a huge and complicated circuit with many resistors, then the effective resistance is the total resistance of the circuit.
