12 volts only refers to the voltage, to be able to say anything about charge time you also need to know the capacity rating in amp hours of the batteries. Assuming lead-acid batteries the charger needs to go to > 14.4 V and then a proportional amount of amps as compared to the capacity rating of the batteries. A rough approximation is that batteries needs to be charged with about 1.4 times their amp rating. An 1 Ah battery would need 2 hours on a 0.7 amp charger for instance.

The ground wire should go from the dryer directly back to the distribution panel. An external ground wire is not required. The ground wire that is in the cord set that is connected to the frame of the dryer and the ground wire that is in the feeders coming from the distribution panel, that is connected to the ground terminal in the dryer receptacle, is all that is required to satisfy the code requirement.
SCM CT is a normal CT which is connected in two phase of the turbines & its terminals are connected to the AVR. Depending on the load on the turbine the current increases & accordingly it gives the input to the AVR so as to develop the required field to generate the same load without any dip in the voltage.
To find the voltage drop over a resistor, you measure it with a voltmeter connected across the resistor. You also need to make sure the impedance of the voltmeter is high enough to not shift the effective resistance more than the required accuracy of the measurement.
If more ampere-hours (or CCA) are required, two (or more) new and identical 12-volt batteries can be connected in parallel. If you connect two 12-volt batteries in parallel, and they are identical in type, age and capacity, you can potentially double you original capacity. If you connect two that are not the same type, you will either overcharge the smaller of the two, or you will undercharge the larger of the two. Connect them in parallel, that is + to + and - to -.
The voltmeter is connected in parallel between the two points whose potential difference is required.
A: Never tie two or more batteries in parallel for the reason that a weak battery will drag a good battery down as suspected. A means of equalizing the the load sharing is required like a diode or very small resistance in series
The required resistance is 12/1.5 = 8Ω.Five 40Ω resistors in parallel have an effective resistance of 8Ω.
In parallel circuits all positives go to negatives, in series it is positive to positive,negative to negative. The difference example , if 12 vote batteries are in parallel 2 batteries would produce 24 volts, in series you would boost the time required to depleate the battery, but it would stay at 12 volts.
It depends on what you want to do with the batteries. They can be connected in series to give you a total of 12 VDC. In a series connection a jumper is required between battery one's negative post to battery number two's positive post. If you want to increase the amp hours delivered at 6VDC they can be connected in parallel. In a parallel connection two jumpers are required. Battery one's negative post to battery two's negative post. Likewise the same procedure with the positive posts.
Both AA and D batteries are 1½ volts. A D battery is used where more current is required - it can deliver more power for longer. For typical batteries with alkaline chemistry: The typical capacity of a D battery is 12000 to 18000 mAh. The typical capacity of an AA battery is 1200 to 2500 mAh. Two AA batteries in parallel will supply twice their current rating, about 2400 to 5000 mAh. You would need 8 to 10 AA batteries in parallel to supply the current of a D battery.
The starter motor of a diesel generator is a DC motor. Depending on the size of the diesel engine the starter motor could be 12 volts or 24 volts. Sometimes more that one battery is used at the specific voltage. These batteries are connected in parallel to create more amp hour cranking power.

There are no batteries required. The kid sits on it and spins it.
Separate devices should always be hooked up in parallel, and not series. Therefore, you would combine the total current requirement, which in this case is 600mA or 0.6A. You would therefore need a 9V power supply that is capable supplying at least 0.6A. It depends on whether the devices are connected in series or parallel or some combination of the two. The current in a series circuit is the same throughout the circuit. The current in a parallel circuit is the sum of the current in each parallel branch If the three devices are connected in series, the required current is 200mA. If the three devices are connected in parallel, the required current is 600mA The total power required by a circuit is the sum of the power consumed by each component. It doesn't matter if the devices are connected in series or parallel. Power = voltage x current. If the three devices are in series, the power consumed by one of them is 9 x .2 = 1.8 watts. The total power consumed is 1.8 x 3 = 5.4W If the three devices are connected in parallel, the power consumed is 9 x .6 = 5.4W Notice that the power consumed is the same for the series and parallel combination. The battery (or power supply) must be able to supply 5.4 watts.
