Find the symbol of fixed resistor?

How do you find resistors in parallel?
Measure the voltage appearing across each resistor. If they are identical, and equal to the supply voltage, then the resistors are in parallel.
How to find Equivalent resistance when you have both parallel and series resistors?
To find equivalent resistance when you have both parallel and series resistors, start simple and expand... Find the smallest part of the circuit, such as a pair of resistors in series or a pair of resistors in parallel, and compute the equivalent single resistor value. Repeat that process, effectively covering more and more of the circuit, until you arrive at a single resistance that is equivalent to the circuit. For resistors in series: RTOTAL = R1 + R2 For resistors in parallel: RTOTAL = R1R2/(R1+R2)
Who discovered Resistor?
Resistance, and therefore resistors, are a part of any electrical conductor. They were not created but rather, discovered and put to use in electrical and electronic circuits.
What is the current flow in a 12VDC circuit with two 24 ohm resistors in parallel?
In a parallel circuit, the same (supply) voltage will appear across each branch. So, in your example, 12 V will appear across each of the 24-ohm resistors. To find the current through each resistor, then, you simply divide the supply voltage by the value of that resistor. Since the supply current is the sum of the two branch currents, to find the supply current, you simply add together the currents passing through each resistor.
What is the effect on the total resistance if increase in resistors in series?
That depends ... in a very interesting way ... on whether they are connected in series or in parallel. -- If the resistors are in series, then the total resistance increases when you add another resistor, and it's always greater than the biggest single one. -- If the resistors are in parallel, then the total resistance decreases when you add another resistor, and it's always less than the smallest single one.
Why might blower fan quit on 88 astro van It had been running on high only then got intermittent A tap on the motor would sometime start it Reads 12vdc at lead and ground at all speeds Runs sometimes?
I think the problem is with the heater motor resistor pack which you will find located near the fan motor. Open the hood and look to the left side corner of the fire wall. I have a 95 Astro and my resistor pack is located on top of the heater blower housing. I have changed many of these resisters on different makes and have found them to have their resistors rusted. The resistors are made of wire and they rtust and burn out. Find the small plug that goes to the resistors and you will find a a plate which has two screws, one on each end of the resistor pack. Remove the two screws and pull out the resistor pack. You can either get a used one from the junk yard or purchase one from a Chevy dealer. The resistor is used to control the different fan speeds and is located in the the blower housing so that the fan helps cool the resistors when the fan is running.

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 equivalent wattage when different wattage resistors are connected in parallel?
In order to determine this, it will be necessary to find which resistor 'maxes out' at the lowest voltage. This can be found using the equation Vi=sqrt (Pi*Ri) for each resistor, where Pi is the power rating of resistor i and Ri is the value of resistor i. Once this is found, the power dissipation of each other resistor can be found using the equation Pi=(Vl^2)/Ri, where Vl is the voltage that maxes out the resistor which maxes out at the lowest voltage, and Ri is the resistance of each resistor. The equivalent power rating would then be the sum of the power dissipated across each resistor.
What kinds of circuits need precise resistors?
Timing circuits, and any circuit that depends on the resistor value being fairly precise, such as voltage dividers and comparators. Old story....engineers knew that you couldn't pick through a bunch of loose precision resistors to find close tolerance resistors....The manufacurer already took the close precision resistors and sold them separately. This is not so true these days. Even low tolerance resistors might be high precision. Usually the manufacturer will fill the loose precision needs with parts better than required.
How do you find the resistance of a series circuit with n identical resistors?
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.
