What is used as a diagnostic tool to test the functionality of a defective device such as a power supply but can also be used to test coaxial serial and parallel cables as well as fuses and resistors?

You likely mean a multimeter. A multimeter tests voltage (voltmeter), current (ammeter) and resistance (ohmmeter). You would need a high impedance one to help prevent blowing sensitive circuits, and digital ones tend to be high impedance.

What picture represents two resistors wired in parallel?
It represents that two resistors are connected in parallel.
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 do you connect several resistances if you want to decrease in total resistance without reducing the number of resistors?
The resistors should be connected in parallel .
What are advantages of a series combination of resistors?
parallel combination of resistors are used in house circuits
What is your observation of resistors in parallel resistors?
RParallel = 1 / Summationi=1toN (1 / Ri)
Two resistors are connected in parallel to a battery What must the votlage across these two resistors?
Both resistors will have the voltage of the battery.
How do resistors act in parallel?
Parallel resistors act like a resistor smaller than the smallest parallel resistor. Calculate as 1/(1/R1+1/R2+1/R3...)
How are parallel resistors connected?
If you need a resistor of a certain value, and you have no resistors with small enough values,you can create the one you need by connecting several of those you have in parallel.The effective net resistance of resistors in parallel is always less than the smallest individual.And the more resistors you add in parallel, the smaller the net effective resistance becomes.
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)
Does power decrease when adding resistors in parallel circuit?
no
How many 75K resistors must be put in parallel to provide a total resistance of 15K?
5000 For Parallel resistors: Rtotal = R / N Rtotal is total resistance R = Value of resistors N = number of resistors 15 = 75000 / N N = 5000
Does you add the shorted resistors in finding the total resistance?
When resistors are wired in series, their resistances are added to find the total resistance. If they are run in parallel, or series-parallel, the formula is different
