The sum of currents across the resistors equals the currents through the source in which type of circuit?
In parallel circuit the current through the resistors are different in values depending upon the values of resistors. But the sum of the currents across all the resistors will be equal to the current through the sourcgsvg bdjasuhafyuhda
What type of circuit has all its resistors in the same path?
A series circuit
What the values of the three resistors 30k ohms 15k ohms and 10k ohms total?
It depends if the are in series or parallel. In series: 55K ohms In parallel: 5K ohms It really all depends brah.
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.
Why resistors are not used in filter circuits?
You want a filter to remove energy at only certain frequencies, and not to have any affect on all the others. Resistors just dissipate energy, regardless of what its frequency may be.
How do you draw this you have three 20 ohm resistors available. how would you connect these three resistors to produce a 30 ohm equivalent you must use all three resistors?
2 in parallel (= 10 ohms) and the third in series.
Your bug-zapper does not work at all three weeks old what happen?
If it has resistors check those first.
How do you calculate the equivalent resistance of a circuit of the shape of a cube and a having a resistor of i kilo ohm in every branch?
Given twelve 1 KOhm resistors, connected in the shape of a cube, in order to determine the net resistance between opposite corners, first draw the cube in two dimensions. (Try this at each step before continuing, so you can understand the lesson as it unfolds.)There are three resistors leaving the initial vertex, and three resistors entering the final vertex. In between those six resistors, are six more resistors, each pair connected together on one end, and to two other resistors on the other end.If every resistor has the same value, then (by symmetry), the voltage on the ends of the first three resistors must be the same. Similarly, the voltage on the ends of the last three resistors must be the same.If two points in a circuit have the same voltage, then (for purposes of analysis) you can consider them to be shorted together. That short does not change the results, as there is no current flowing through that short.With the bottom ends of the first three resistors shorted, and with the top ends of the last three resistors shorted, the circuit degrades into three resistors in parallel, in series with six more resistors in parallel, in series with three more resistors in parallel.Three 1 KOhm resistors in parallel have a net resistance of 333 ohms. Six have a net resistance of 167 ohms. Two 333 ohm resistors and one 167 ohm resistor in series have a net resistance of 833 ohms, or 5/6 of 1 KOhms.Note: This technique does not work if the resistors are not all the same value. In that case, you would need to solve 12 equations in 12 unknowns, looking at the partial currents in each branch.
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
When three resistors are connected in series the amount of voltage that is measured across each one is determine by what?
The voltage drop across each resistor is determined by the amounts of resistance in the 3 resistors and all the rest of the resistances in the electrical circuit.
Active component in resistors and capacitors?
Resistors, capacitors, inductors, diodes are all passive components.
What are the ratings and certificates for Three for All - 1975?
Three for All - 1975 is rated/received certificates of: UK:U
In a circuit the voltage across all resistores is the same?
It depends upon the connection of the resistors, if the resistors are connected in parallel then the voltage is same where as in case of resistors connected in series the voltage is different across different resistors.
What is carbon composition resistors?
Carbon composition resistors are resistors that are made with carbon or graphite mixed with a binding material. It's one type of resistors among several. There are also carbon-film resistors and metal-film resistors. Out of all the resistors, carbon-film resistors have the greatest tolerances and changes to temperature fluctations. Thus, they are used in applications where precision isn't critical and where temperature will not change drastically.
What products use resistors?
allmost every electronic devices uses resistors..(it is needed in all circuits)
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.
In a circuit the voltage across all resistors is the same.?
lf all resistors are in parallel, yes. If they are in series, not necessarily - this depends on the resistor values (if they are all the same, then yes, if not no).
