I'm stuck on these questions guys. Any help is appreciated
1) How great is the terminal voltage on a battery while measuring its maximum current?
2) How great is the current delivered by a battery while measuring its EMF?
3) What would happen if you alter the polarity of one of the batteries in a circuit containing 2 batteries in series?
4) How many batteries are needed in order to increase both EMF and the maximum current (in a circuit containing 2 batteries)? How the batteries must be connected in order to achieve this(series or parallel)?

Part A The circuit shown in (Figure 1) is used to make a magnetic balance to weigh objects. The mass in to be measured is hung from the center of the bar, which is in a uniform magnetic field of 1.90 T directed into the plane of the figure. The battery voltage can be adjusted to vary the current in the circuit. The horizontal bar is 64.0 cm long and is made of extremely lightweight...

1- Capacitor B has half of the capacitor A. Compare the load of capacitor A with capacitor B charge when the two capacitors remain connected in series with a battery for a long time. 2- A capacitor immersed in the air has capacitance equal to 12.5 μF when the potential difference at its terminals is 24.0V. If we insert a constant material dielectric equal to 3.75 between the capacitor plates, filling the space between them completely, (a) how much energy...
