When three resistors 5 ohm 10 ohm and 15 ohm are given to you find the least and maximum possible value of resistance that can be obtained using them? Answer. Answer: Explanation: The value is depend on that these resistors are in parallel or in series. If in
series- resistance will be 30 ohms
.
When the resistance 5 ohm 15 ohm and 60 ohm connected parallel the equivalent resistance will be?
3.5
is the right answer .
What would the equivalent resistance be for a 15 and 5 ohm resistor connected in parallel Expalin your answer?
current resistance is 1 by 15 ohm + 1 by 10 + 1 by 5 ohm equal to
30/11
.
What is the maximum resistance which can be made using 5 resistors each of 5 ohm?
the maximum resistance which can be made using 5 resistors each of 1/5 ohms is
1 ohm
.
What is current through the 10 ohm and 15 ohm resistor?
Answer: Resultant current through the circuit is
0.36 Amp
.
What is the effective resistance?
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.
How do you find 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.
Why is resistance less in parallel?
Resistors in parallel
In a parallel circuit,
the net resistance decreases as more components are added
, because there are more paths for the current to pass through. The two resistors have the same potential difference across them. The current through them will be different if they have different resistances.
What is the current in the 50 Ω resistor?
The current in the 50-Ω resistor in the circuit shown is:
6 12V 4.0 6
.
How do you calculate equivalent resistance?
- The equivalent resistance is the algebraic sum of the resistances (Equation 10.3. …
- 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.
What is maximum resistance?
It is know to us , combining resistances in parallel reduces equivalent resistance and combining resistances in series increases equivalent resistance. To get maximum possible resistance, one has to combine all 5 resistors in series. Rmax=R1+R2+R3+R4+R5 Rmax=R+R+R+R+R=5R. Rmax=5×51=
1Ω
What is the maximum and minimum resistance which can be made?
While equivalent resistance increases when resistors are joined in series e.g.,
Req = R1 + R2 + R3 +
…. + Rn. it Means, we can get minimum resistance when all the given resistors will join in parallel. And we can get maximum resistance when all the resistors will join in series .
How do you find minimum resistance?
Take the nominal value and multiply it by 1 + your tolerance, which is (1
+0.1
). Then take the nominal value and multiply it by 1 – tolerance, or (1-0.1).
What is the current flowing through the 10 ohm resistor?
So the current flowing through the circuit is
0.6 Amperes
.
What is the current in the 10 Ω resistor write you answer in amperes?
This gives the current flowing across the 10 ohm resistor equal to 6/10.8 =
5/9 amp
.
What is the difference between effective resistance and 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.
