When connected in series, the overall effective resistance of a bunch of individual resistors is
the sum of the individual resistances. It's always more than the resistance of any individual.
When connected in parallel, the reciprocal of the overall resistance of a bunch of individual resistors
is the sum of the reciprocals of the individual resistances. It's always less than the resistance of any
individual.
When two resistors are connected in parallel, the overall effective resistance of the pair is
(the product of the two individual resistances) divided by (the sum of the two individual resistances).
It's always less than the smaller individual resistance.
What else can I help you with?
Is resistance applied in series or parallal?
A: They are applied both and combination of both
If a circuit contains 3-ohm resistance in a series what is the equivalent resistance of combination?
Equation for Equivalent Resistance in Series isReq= R1+R2+R3+...........If each resistor is equal to 3OhmsthenReq= R1+R2+R3Req=3+3+3Req=9 OhmsThe Equivalent resistance is 9 Ohms.
How do you measure alternating current voltage and resistance?
You measure current by inserting an amp meter in series with the circuit or using a clamp-on meter to measure current by induction. You measure voltage with a volt meter across the supply. You measure resistance in ohms across the resistance. Luckily all these functions are in the same meter in most cases.
Three resistances each of 4 ohm are connected to form a triangle the resistance between any two terminals is?
That's like having a series combination of 4 + 4 ohms, in parallel with another resistance of 4 ohms. Calculate the series resistance, then use the parallel formula to combine it with the third resistance.
How do you measure Input high voltage?
You can measure high voltage by using Potential Transformer (PT). or by using utility meter or power manager. ANSWER: Adding a hi resistance in series with a low resistance and measuring that voltage drop. If the resistance is known then current is determined and the source can be calculated. transformers do not work well with DC,
What is the ratio of equivalent resistance of series and parallel combination of n equal resistance to the equivalent resistance on parallel combination?
The ratio of the equivalent resistance of series combination to the parallel combination of n equal resistors is (n^2 - 1)/n.
What is series combination of resistance?
Add all the individual resistance values.
How is the voltage drop across each resistance of series combination related to the correspoding resistance?
The voltage across each series component is proportional to its resistance, and their sum is equal to the voltage between the ends of the complete series string.
Is resistance applied in series or parallal?
A: They are applied both and combination of both
How do you measure the unknown resistance?
You can measure an unknown resistance by using a multimeter set to the resistance measurement function. Connect the unknown resistance in series with the multimeter and apply a known voltage across them. The multimeter will display the resistance value based on the voltage and current readings.
How do you measure resistance in series circuit?
Using an Ohmeter open either end and follow above advice
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.
What units do you measure resistance in?
Your measure resistance in OHMS ΩOhms.
How do you measur ampere?
You use an "amp gauge" to measure amps in an actual circuit. It is hooked in series with the load. It can be placed anywhere in the circuit as long as it is hooked in series. Mathematically, you have to know the resistance, or wattage and voltage of a circuit. Volts=amps*resistance or amps=volts/resistance, or resistance=volts/amps. Ohms law!

A 3.0 lamp and a 6.0 lamp are connected in serieswhat is the total resistance of the combination?
In a series circuit, the total resistance is the sum of the individual resistances. So, the total resistance of the 3.0 lamp and 6.0 lamp connected in series would be 3.0 + 6.0 = 9.0 ohms.
