What is the resistance between any two of the corners if Three 3 ohm resistors are connected such that it make triangle.?
2 ohms. It is like connecting two 3 ohm resistors in series and then these two series resistors are connected in parallel with third 3 ohm resistor in parallel
A 22 k and Ohm and 12 k and Ohm resistor are connected in series across a 68 V source how is the voltage divided?
If the resistors are in series the voltage can not be divided, as it has to pass first through one then the other. The amount of current that flows through a set of resistors in series will be the same at all points and the total resistance in the circuit must be equal to the sum of all the individual resistors added together. In other words the 22k and 12k Ohm resistors are the sames as a single 34k Ohm resistor.
Define zero ohm resistor.?
A zero-ohm resistor does not exist, so we are talking about an ideal resistor. An ideal resistor is needed for description in a circuit, where we lump all wire/parasitic resistances into discrete resistors, but the wire joining two discrete resistors is considered to have no resistance. My definition: a zero-ohm resistor is an ideal resistor that does not consume energy when a current exists in the resistor. Alternatively, a zero-ohm resistor is an ideal resistor that cannot sustain any potential drop when a current is on. Thirdly, a zero-ohm resistor is an ideal resistor that will conduct an infinite current when a voltage is applied across it.
A 120 ohm resistor a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source What is the effective resistance of the three resistors?
To find the effective resistance of resistors connected in parallel, you can use the following formula: 1/Reff = 1/R1 + 1/R2 + 1/R3 + ... In this case, we have three resistors connected in parallel: a 120-ohm resistor, a 60-ohm resistor, and a 40-ohm resistor. 1/Reff = 1/120 + 1/60 + 1/40 To simplify the equation, we need to find a common denominator: 1/Reff = (1/120) + (2/120) + (3/120) 1/Reff = 6/120 Now, let's invert both sides of the equation: Reff = 120/6 Reff = 20 ohms Therefore, the effective resistance of the three resistors connected in parallel is 20 ohms.
What is the value of 1E5 resistor?
According to the EIA-96 system which applies to SMD resistors, it means 10K (10,000 ohm), 5% tolerance.
I have three identical resistors all at 100 ohms in what combination can I put them to obtain a resistance of 66.7?
If you have three 100 ohm resistors, and you want an equivalent resistor of 66.7 ohms, put two resistors in series, and then parallel the third resistor across the first two. Resistors in series: R1 + R2 Resistors in parallel: R1 * R2 / (R1 + R2) This example: Two 100 ohm resistors in series: 100 + 100 = 200 A 100 ohm resistor in parallel with a 200 ohm resistor: 100 * 200 / (100 + 200) = 66.7
A 120 ohm resistor a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source. What is the effective resistance of the three resistors?
The effective resistance of those three resistors in parallel is 20 ohms. And it makes no difference what the power source is, or whether they're even connected to a power source at all. As soon as those three resistors are in parallel, their effective resistance is 20 ohms immediately, even if they're still in the drawer.

2 ohms. It is like connecting two 3 ohm resistors in series and then these two series resistors are connected in parallel with third 3 ohm resistor in 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.
What is the smallest number of resistor to provide 4 ohm if only 3 ohm are available?

Decade resistor box?
A variable range of resistors built inside a box that can be varied as per our convenient. For example a set of kilo ohm resistors will be there,if u want 3 kilo ohm resistor then using the knob u can change the resistor value to your desired value. similarly there will be another set of resistors in mega ohm etc
When 2 resistors are connected in parallel r1r2 are?
Two resistors connected in parallel are 1/2 the sum of their resistance. The resistance of two resistors connected in series is the sum of their resistance. For example: The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in parallel is 100+200 divided by 2 = 150 ohms. The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in series 100+200= 300 ohms.
A 120 ohm resistor a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source What is the effective resistance of the three esistors?
The effective resistance of three resistors, 120 ohm, 60 ohm, and 40 ohm, in parallel is 20 ohms.RP = 1 / sum (1 / RN)RP = 1 / (1 / 120 + 1 / 60 + 1 / 40)RP = 20The voltage applied, 120V, does not change the outcome. The power, however, of the three resistors is 120W, 240W, and 360W respectively. This is a lot of power, so please do not attempt to do it for real.

How many amps in the related link circuit between A and B?
The related link describes a 100 volt source driving three unknown resistors in series, with a fourth resistor of 10 ohms in parallel with one of the three resistors. It is stated that the voltage across the 10 ohm resistor is 20 volts. By Ohm's Law, current is voltage divided by resistance, so the current through the 10 ohm resistor is 2 amperes. Since you were provided with the voltage across the 10 ohm resistor, it does not matter what the value of the other three resistors is. However, and this is important to note... The voltage source and three resistors are not shown with any kind of connection to ground, so the circuit, as drawn, is invalid. Nevertheless, the voltage stated across the 10 ohm resistor was 20 volts, so there must be some kind of connection, and that was the basis for the calculation above. If, on the other hand, the 20 volts is referenced to the voltage source, then the current from A to B is zero, because there is no circuit involving the 10 ohm resistor.
What are the main condition for resistors in parallel?
Two resistors wired in parallel means that both resistors are soldered together to equal the value of a smaller resistor value. Both resistors will be connected to the same line on the circuit board and then both will terminate on the same final line they are assigned to. Thus, a pair of 100k ohm resistors can take the place of one 50k ohm.
If 2 resistors or resistance 10 ohm and 5 ohm resp r connected in parallel which will get more heated?
The 5 Ohm resistor will have more current passing through it than the 10 ohm resistor. Since the resistors are in parallel the Voltage across each resistor is the same. Power or the amount of heat in terms of the question can be derived from Power = Voltage * Current. Ohm's law tells us that the current flowing through a resistor is equal to the Voltage across the resistor divided by the resistance. The formula for power is then the Voltage * Voltage / Resistance. Since V^2 / 10 is smaller than V^2 / 5 we know that the 5 ohm resistor will always have more power dissipated than the 10 ohm resistor.
