To get the voltage of batteries in series you have to sum the voltage of each cell in the serie. To get the current in output of several batteries in parallel you have to sum the current of each branch .
The equivalent resistance is This parallel combination is in series with the other two resistors, so the equivalent resistance of the circuit is The voltage supplied by the battery is therefore 5. One way to check the consistency of your results is to calculate the power supplied by the battery and the power dissipated by the resistors.
Power can also be calculated using either P = IV or P = V 2 R P = V 2 R, where V is the voltage drop across the resistor (not the full voltage of the source). The same values will be obtained. The easiest way to calculate power output of the source is to use P = IV, where V is the source voltage. This gives P = (0.600 A) (12.0 V) = 7.20 W.
Figure 10.13 A simple series circuit with five resistors. In a series circuit, the equivalent resistance is the algebraic sum of the resistances. The current through the circuit can be found from Ohm’s law and is equal to the voltage divided by the equivalent resistance. The potential drop across each resistor can be found using Ohm’s law.
We’ve seen the formula for determining the power in an electric circuit: by multiplying the voltage in “volts” by the current in “amps” we arrive at an answer in “watts.” Let’s apply this to a circuit example: In the above circuit, we know we have a battery voltage of 18 volts and a lamp resistance of 3 Ω.
Power should be greater for the same devices in parallel compared with series, and so on. The total resistance of an electrical circuit with resistors wired in a series is the sum of the individual resistances: Rs = R1 + R2 + R3 +…. Each resistor in a series circuit has the same amount of current flowing through it.

Resistors in Series and Parallel | Physics
The easiest way to calculate power in watts (W) dissipated by a resistor in a DC circuit is to use Joule''s law, P = IV, where P is electric power. In this case, each resistor has the same full current flowing through it. By substituting Ohm''s law V = IR into Joule''s law, we get the power dissipated by the first resistor as

9.4: Resistivity and Resistance
Since the resistance is calculated as (R = rho dfrac{L}{A}), the resistance increases as the foil tracks are stretched. When the temperature changes, so does the resistivity of the foil tracks, changing the resistance.
