Which circuit has the highest equivalent resistance?
the series circuit has the higher equivalent resistance.

Then the series calculations for resistors so let’s go ahead and write that series r eq is equal to r1 plus r2 plus r3.
Is equivalent resistance greater in parallel or series?
The current through a series connection of any number of resistors will always be lower than the current into a parallel connection of the same resistors, since the equivalent resistance of the series circuit will be higher than the parallel circuit.
What is maximum equivalent resistance?
Maximum resistance can be obtained by series combination and minimum resistance can be obtained by parallel combination. For series combination; equivalent resistance. R=R1+R2+R3.
What is the equivalent resistance of a parallel circuit?
How do you calculate two resistors in parallel? Take their reciprocal values, add the two together and take the reciprocal again. For example, if one resistor is 2 Ω and the other is 4 Ω, then the calculation to find the equivalent resistance is 1 / (1/2 + 1/4) = 1 / (3/4) = 4/3 = 1.33.
What is equivalent resistance of the circuit?
The equivalent resistance is where the aggregate resistance connected either in parallel or series is calculated. Essentially, the circuit is designed either in Series or Parallel. Electrical resistance shows how much energy one needs when you move the charges/current through your devices.
Where is the most resistance found in a circuit?
Most of the resistance in circuits is found in components that do specific work, such as bulbs or heating elements, and in devises called resistors. Resistors are devises that provide precise amounts of opposition or resistance to current flow.
Does a parallel circuit have more resistance?
The total resistance in a parallel circuit is always less than any of the branch resistances. Adding more parallel resistances to the paths causes the total resistance in the circuit to decrease.
Why do parallel circuits have less resistance?
3:125:46Resistance in Parallel Circuits – YouTubeYouTubeStart of suggested clipEnd of suggested clipLaw is that when we have lower resistance. We have more current lower resistance equals more currentMoreLaw is that when we have lower resistance. We have more current lower resistance equals more current so it stands to reason that if you have multiple parallel circuits and you add up those currents.
What is the maximum and minimum resistance?
The minimum resistance would be all the devices in parallel. THe maximum would be all the devices in series.
How do you find the minimum equivalent resistance?
So, minimum resistance (R) = 1.25 Ohm. If N number of resistors connected in series, then the equivalent resistance (REQ) = r1 + r2 + r3 +… + rN.
What is the formula for equivalent resistance?
2] Equivalent resistance formula for parallel resistance: 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.
How do you find the smallest equivalent resistance?
If you have two or more resistors in parallel, look for the one with the smallest resistance. The equivalent resistance will always be between the smallest resistance divided by the number of resistors, and the smallest resistance.
How do you solve equivalent resistance problems?
Find equivalent resistance of the network. Find current in each resistor. Find voltage drops VAB,VBC,VCD. Medium.
How do you find the equivalent resistance between two points?
The two resistances R1 and R2 of 4 ohms are in series therefore their equivalent resistance,R’ = 4 Ω + 4 Ω = 8 ΩNow the resistances R’, R3 and R4 are in parallel so the equivalent resistance of the circuit would be.Therefore the equivalent resistance between the two points A and B in the given circuit is 1.85 Ω.
What is the equivalent resistance of a circuit?
The equivalent resistance of the circuit is the amount of resistance that a single resistor will require in order to equalise the total effect of the set of resistors present in the circuit. For parallel circuits, the equivalent resistance of a parallel circuit is given …
Which option has the smallest euqivalent resistance?
So, from the above calculation it is seen that the third option has the smallest euqivalent resistance value.
How many resistors are in a parallel circuit?
Although each branch gives 4 of resistance to any charge flowing through it, only one-half of all the charge flowing through the circuit may meet 4 of resistance of that branch. 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.
How do resistors work?
In order to improve the net resistance, the resistors must be wired in series and the resistors must be connected in parallel to reduce the resistance.
What happens when two resistors are wired in series?
Then the two resistors are wired in series and their equal resistance increases between their endpoints.
How to find current through a battery?
To find the current through the battery we need to find the equivalent resistance of the circuit. The total current I is divided into and . The current passes through two resistors as they are connected in series and have the same current. The current passes through and resistors as they have the same current.
What is the measure of how much a device or material can resist the movement?
When a circuit has more than one circuit component in it, there should be a way to calculate the total effective resistance of the entire circuit or for just one part of the circuit. Before we discuss what equal resistance is, we can describe resistance. Resistance is a measure of how much a device or material can resist the movement …
