AS:
total power = P1 + P2 + P3 + .......
so,
total power = 5(50mW)
= 0.25W
total power dissipated by the five resistors is 0.25W.

Three resistors having a value of 10 omes each are connected in series to a 300 volts power source what is the total resistance of this circit?
Three resistors having a value of 10 ohms each, when connected in series, have a total effective value of 30 ohms, even if they're wrapped in tissue, stuffed into a box, and stored in the back of your sock drawer. What, if anything, they're connected to makes no difference. If you take the series string of three resistors out of the box and connect it to the terminals of a 300-volts power source, then the string will conduct a current of 10 Amperes. Each resistor will dissipate 1,000 watts and heat rapidly, until the first one either melts or explodes, whereupon the series circuit will open and the flow of current will cease.
Does more current flow through a parallel circuit than a series circuit?
Two resistors in parallel are equivalent to a single component with a lower resistance than either of the pair. Two resistors in series are equivalent to a single component with a resistance equal to the sum of the pair, therefore a higher resistance. For a given potential difference, more current in total will flow through two resistors in parallel than through the same resistors in series.
Did the the total voltage across the resistors does not depend on the resistor value?
It depends on where and how the resistor is placed in a circuit. A string of series resistors will split the voltage across all them depending on their values. All of the resistors in parallel will have the same voltage across all of them no matter what their resistance is.
When a 30.0-V emf device is placed across two resistors in series a current of 14.0 A is flowing in each of the resistors. When the same emf device is placed across the same two resistors in parallel?
There is insufficient information in the question to answer it. 30 volts generating 14 amperes means the two resistors have a total series resistance of 2.143 ohms. Since no relationship was stated, we don't know the value of the individual resistors. If the two resistors had the same resistance, the net parallel resistance would be 0.536 ohms, and a current of 56 amperes would flow.
What is the total voltage drop across a set of resistors in series?
Simply add all of the component's resistances together and that will give you circuits total resistance. If you're dealing with a 'series-parallel', or 'parallel' circuit, the equations will change, but in a simple series circuit, the total resistance is just the total of all the component's resistance.
What is your observation of resistors in series?
I observe that the total effective resistance of several resistors in series is the sum of the individual resistance values of the individual resistors.
What is the rule for finding the total resistance of a number of resistors connected in series?
If the resistors are in series, then the total resistance is simply the sum of the resistances of each resistor.
What is the total resistance in a circuit that contains three 60 resistors connected in series?
The total effective resistance of resistors in series is the sum of the individual resistances.Three 60-ohm resistors in series have a total effective resistance of (60 + 60 + 60) = 180 ohms.
How much power does a string of 6 4.5v 40ma led's consume?
The total power of a series of resistors is equal to the sum of the power dissipated by individual resistors. In this case, each resistor consumes 4.5v*.04amps which is equivalent to 1.08 watts. Since there are 6 resistors, 6.48 watts of power are consumed.
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.
Do additional resistors affect current in a series circuit?
Yes, additional resistors affect current in a series circuit by increasing the total resistance, which decreases the total current.
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
What is true about series connections of resistors?
The more resistance there is, the harder it is for current to flow. So the total resistance is the sum of all resistors in series.

What is the equivalent resistance of a pair of 8 ohm resistors in series circuit?
Two eight-ohm resistors in series would have a total resistance of 16 ohms. Two eight-ohm resistors in parallel would have a total resistance of four ohms.
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.
Do additional resistors affect power?
Of course. Additional resistors change total resistance, which changes current, which affects power.
