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

. The resistors can either be connected in parallel combination or series combination.

What is the equivalent resistance between?

What is Equivalent Resistance? The equivalent resistance is defined as a point where the total resistance is measured in a parallel or series circuit (in either the whole circuit or in a part of the circuit). The equivalent resistance is defined

between two terminals or nodes of the network

.

What is difference between effective resistance and equivalent resistance?

What is the difference between Equivalent Resistance and Effective Resistance? Equivalent resistance is a

purely resistive property

, which does not change with any other variable. Effective resistance is another name given to the impedance. Impedance is a property, which changes with the frequency of the signal.

How do you find the effective resistance of a circuit?

Total effective resistance of the circuit, R = R

. When they are joined in parallel the total resistance is p. If s=np then the minimum possible value of ′n′ is. A.

What is the total resistance across?

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm’s Law:

R = V / I

. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance R
_T
= 9 volts / 3 amps = 3 Ω.

What is the total resistance of two resistances of 4 ohms and 6 ohm are connected in parallel?

Hence , Total resistance for series combination is

10Ω

What is the total resistance across A and B in the circuit shown in Figure 4.9 8?

that ans is parallel to it so final ans is

What will be the effective resistance in the above circuit answer?

Answer: The effective resistance of the circuit is

the sum of individual resistances of the resistors present in the circuit

. The effective resistance of the series circuit is always larger than the greatest resistance in the circuit. Current through various electrical components connected in series is the same.

What is the symbol of effective resistance in physics?

The unit for resistance is an ohm and is given the symbol

Ω

(upper case Greek omega). Rearranging I = V/R gives R = V/I, and so the units of resistance are 1 ohm = 1 volt per ampere: 1Ω=1VA 1 Ω = 1 V A .
