How do you find the equivalent resistance of a network?
The equivalent resistance of a number of resistors connected in parallel can be computed using the reciprocal of the resistance i.e. \frac{1} {R}. The reciprocal of the equivalent resistance will be equal to the sum of the reciprocals of each resistance. The unit of resistance is the Ohm i.e. \Omega.
How do you find the equivalent resistance of a resistor?
The equivalent resistance is the algebraic sum of the resistances (Equation 10.3. 2): RS=R1+R2+R3+R4+R5=20Ω+20Ω+20Ω+20Ω+10Ω=90Ω. The current through the circuit is the same for each resistor in a series circuit and is equal to the applied voltage divided by the equivalent resistance: I=VRS=9V90Ω=0.1A.
How do you find the equivalent resistance for a number of resistors in series?
equivalent resistance of resistors in series : R = R1 + R2 + R3 + A series circuit is shown in the diagram above. The current flows through each resistor in turn.
How to calculate the equivalent resistance of a network?
The equivalent resistance of a network is that single resistor that could replace the entire network in such a way that for a certain applied voltage V you get the same current I as you were getting for a network. Where, R1, R2…..Rn the given resistors.
