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 do you place 3 resistance to get the total resistance of 1 ohm?
It depends on the resistance of each resistor. If each resistor, for example, is 0.333 ohm, then you could connect them in series. If each resistor, for example, is 3 ohms, then you could connect them in parallel.
How to identify a 470 ohm resistor?
Resistors are color coded to denote the value of the resistor as well as the multiplier. In your case a 470 ohm would be colored as Yellow Violet Brown corresponding to 4, 7 and a multiplier of 10^1.
How can you connect resistors to produce an equivalent resistance which is the same as the resistance of each individual resistor?
You can connect 4 resistors in series-parallel, i.e. two in series, both in parallel with another two, and the effective resistance would be the same as one resistor. Similarly, you can connect nine resistors in 3x3 series-parallel, or 16 resistors in 4x4 series-parallel, etc. to get the same resistance of one resistor.
6 equal resistors of 1 ohm each are connected to form the sides of a hexagon ABCDEF calculate the resistance offered by the combination if the current enters at A and leaves at D?
1.5 ohms. Two 3 ohm resistors in parallel.
Do three 1m ohm resistors equal a 3m ohm resistor?
Only if you connect then in series. RSERIES = Summation1toN (RN) RPARALLEL = 1 / Summation1toN (1 / RN)
What is the smallest number of resistor to provide 4 ohm if only 3 ohm are available?
4, 1 3 ohm resistor in series with 3 3 ohm resistors in parallel.
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.
Calculate the power used in 2ohm resistor in each what circuits- 1 a 6V battery in series wid 1ohm and 2ohm resistors 2 a 4V battery in parallel wid 12ohm and 2ohm resistors?
In the first circuit with a 6V battery in series with 1 ohm and 2 ohm resistors, you can use Ohm's Law (P = V^2 / R) to calculate the power used in the 2 ohm resistor. First, find the total resistance of the circuit: 1 ohm + 2 ohm = 3 ohms. Then, calculate the current flowing through the circuit using V = IR. Finally, use P = V^2 / R with the resistance of the 2 ohm resistor to find the power. In the second circuit with a 4V battery in parallel with 12 ohm and 2 ohm resistors, first calculate the equivalent resistance of the parallel circuit using the formula (1/Req = 1/R1 + 1/R2). Once you have the equivalent resistance, use Ohm's Law (P = V^2 / R) to find the power used by the 2 ohm resistor.

A 120 resistor a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source what is the current running though the 40 ohm resistor?
To calculate the total current in the circuit, you first need to find the total resistance by using the formula for resistors in parallel: 1/Total Resistance = 1/120 + 1/60 + 1/40. Once you have the total resistance, you can use Ohm's Law: Current = Voltage / Total Resistance. Finally, to find the current running through the 40 ohm resistor, you divide the total current by the resistance of the 40 ohm resistor.

How will you join 3 resistors of 2 ohm each so that the effective resistance is 3 ohm?
You can achieve an effective resistance of 3 ohms by connecting the resistors in series. Connect two resistors in series to get a combination of 4 ohms. Then, connect this combination in parallel with the third resistor to achieve an overall resistance of 3 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 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.
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 current running through the 120 ohm resister?
To find the current running through the 120 ohm resistor, first calculate the total resistance of the parallel circuit using the formula: 1/total resistance = 1/120 + 1/60 + 1/40. Then use Ohm's Law (I = V/R) with the total resistance to find the total current in the circuit. Finally, use the current divider rule to find the current specifically through the 120 ohm resistor.
