A circuit consists of two resistors of 5 ohms and 2 ohms connected in series if a current of 5 amps in the circuit the power dissipated in the 2 resisters will be?
Two resistors in series, one 5 ohms and one 2 ohms, with a current of 5 amperes, will have a power dissipation of 175 watts.
Ohm's law: Voltage = current times resistance
E1 = I R1 = (5) (5) = 25 volts
E2 = I R2 = (5) (2) = 10 volts
Power law: Power = current times voltage
P1 = I E1 = (5) (25) = 125 watts
P2 = I E2 = (5) (10) = 50 watts
PT = P1 + P2 = 125 + 50 = 175 watts

What is a resistance network?
A resistance 'network' consists of a number of resistors connected together in series, or in parallel, or in series-parallel, or as a complex circuit. A 'complex' circuit is one that is not series, parallel, or series-parallel.
What is a circuit that uses resistors to produce a voltage lower than the source voltage call?
A circuit that uses resistors to produce a voltage lower than the source voltage is called a voltage divider. It typically consists of two or more resistors connected in series, with the output voltage taken from the junction between them. The output voltage can be calculated using the formula ( V_{out} = V_{in} \times \frac{R_2}{R_1 + R_2} ), where ( R_1 ) and ( R_2 ) are the resistances of the two resistors. Voltage dividers are commonly used in electronic circuits for signal conditioning and level shifting.
How is total resistance calculated in a series circuit?
If the circuit consists of resistors only, you simply add the values of all the resistors, in ohms.
Why the net resistance increases in series connection?
series network consists of components i.e resisters connected end to end. since their is only one path for the flow of current. but potential drop across each resister is different. so thats the reason that series network has maximum resistence then the highest resister in combination. the same amount of current passes through each resister.
What is the total resistance if they have equal resistances in series in each of rows in parallel?
If the overall load consists of:'R' = resistance of each individual resistor'S' = number of resistors in each series row'P' = number of series rows connected in parallel,then the effective overall DC resistance of the entire network is[ R S / P ]

What does a voltage divider do and how does it work to divide the input voltage into smaller output voltages?
A voltage divider is an electrical circuit that divides the input voltage into smaller output voltages. It consists of two resistors connected in series. The output voltage is determined by the ratio of the two resistors. The formula for calculating the output voltage is Vout Vin (R2 / (R1 R2)), where Vin is the input voltage, R1 is the resistance of the first resistor, R2 is the resistance of the second resistor, and Vout is the output voltage.
