What else can I help you with?
To connect a pair of resistors so that their equivalent resistance is greater than the resistance of either one should you connect them in series or in parallel?
When many resistances are connected in series, the equivalent resistance is greater than the greatest single resistance. When many resistances are connected in parallel, the equivalent resistance is less than the smallest single resistance.
Why shunt resistance is connected in the parallel?
Shunt means parallel only..................
What is a resistance network?
A resistance 'network' consists of a number of resistors connected together in series, or in parallel, or in series-parallel, or as a complex circuit. A 'complex' circuit is one that is not series, parallel, or series-parallel.
Do 5 1 ohm resistors equal 1 5 ohm resistor?
it depends on how we are connecting them.if 5 1 ohm resistors are connected in series then the equivalent resistance is 5 ohms.if they are connected in parallel then the equi resistance is 1/5 ohms.
Which is the total resistance of a circuit that contains twenty 100 ohms resistors connected in parallel?
When resistors of the same value are wired in parallel, the total equivalent resistance (ie the value of one resistor that acts identically to the group of parallel resistors) is equal to the value of the resistors divided by the number of resistors. For example, two 10 ohm resistors in parallel give an equivalent resistance of 10/2=5Ohms. Three 60 ohm resistors in parallel give a total equivalent resistance of 60/3 = 20Ohms. In your case, four 200 Ohm resistors in parallel give 200/4 = 50 Ohms total.
What is the equivalent resistance of the parallel circuit you have connected?
In principle, it is infinite. I have not connected a parallel circuit in ages.
How is resistivity connected to resistance?
Resistance is connected in parallel with voltmeter or say, voltmeter is connected in parallel with resistance.
Three 8.0-W resistors are connected in series What is their equivalent resistance?
The equivalent resistance of resistors connected in series is simply the sum of their individual resistances. Therefore, the equivalent resistance of three 8.0-W resistors connected in series is 24.0 W.
How do you calculate the equivalent resistance connected together in parallel?
Let the equivalent resistance be R and let there be 3 resistors namely R1,R2 and R3, connected in a parallel way. Now, the relation is: 1/R = 1/R1 + 1/R2 + 1/R3
To connect a pair of resistors so that their equivalent resistance is greater than the resistance of either one should you connect them in series or in parallel?
When many resistances are connected in series, the equivalent resistance is greater than the greatest single resistance. When many resistances are connected in parallel, the equivalent resistance is less than the smallest single resistance.
If additional resistance is connected in parallel with a circuit the supply voltage will decrease?
If additional resistance is connected in parallel with a circuit the supply voltage will decrease?
Three equal resistors connected in series across a voltage source dissipate a power of 10W what sould be the power desipated if same resistors are connected in parallel?
If three equal resistors are connected in parallel, the equivalent resistance will be one-third of the resistance in series. This lower resistance will result in a higher current flowing through the resistors when connected in parallel compared to when they are in series. Therefore, the power dissipated by the resistors in parallel will be greater than 10W.
What is the resistance of 70ohms and 30ohms connected in parallel?
21
What is the ratio of equivalent resistance of series and parallel combination of n equal resistance to the equivalent resistance on parallel combination?
The ratio of the equivalent resistance of series combination to the parallel combination of n equal resistors is (n^2 - 1)/n.
Why ammeter works as short circuited in circuit?
The ammeter is basically a Galvanometer with a small resistance to parallel with it. As we know that, if we connect two resistances in parallel, then the equivalent resistance is equal to the the value which is less than the value of lowest resistance connected in parallel. suppose if we connect 1 ohm & 0.1 ohm in parallel, then the equivalent of it will be 0.0909 ohm (less than 0.1 ohm). means in parallel circuit the equivalent resistance become smaller. as like this a small parallel resistance across galvanometer decreases the value of the value of resistance of it. since it gets very small value, so it connected in series to measure the value of current in the circuit. due to very low resistance, it drops very low voltage on it ( upto can be negligible) so we assume that it works like a short circuit.
What is the difference between connecting resistors in parallel and in series?
When resistors are connected in series, the total resistance is the sum of the individual resistances. When resistors are connected in parallel, the total resistance is less than the smallest individual resistance.
Is a ammeter connected in series or in parallel with the circuit under test?
An ammeter is connected in series. A voltmeter is connected in parallel. ammeter should always be connected in series instead of parallel becoz it is a low resistance device and we know that resistance is inversly proportional to current so more current will pass through it and if it is connected in parallel than it may get damaged
