To find the current in a circuit with 2 batteries connected, you will need to use Ohm's Law. Ohm's Law states that current (I) is equal to voltage (V) divided by resistance (R). In this case, you will need to add the voltages of the two batteries together and divide by the total resistance of the circuit.
Yes, you can use Kirchhoff's Laws to determine the currents and voltages in a circuit with 2 batteries connected. Kirchhoff's Laws state that the sum of the currents entering a junction is equal to the sum of the currents leaving a junction, and the sum of the voltage drops around a closed loop is equal to the sum of the voltage sources in that loop.
In a series circuit, the two batteries are connected end-to-end, creating a single path for current to flow. In this case, the current is the same throughout the circuit and the voltage drops across each component are additive. In a parallel circuit, the two batteries are connected side-by-side, creating multiple paths for current to flow. In this case, the voltage is the same across each component and the total current is the sum of the currents through each path.
To calculate the voltage drop across each component, you will need to use Ohm's Law. Using the formula V=IR, where V is voltage, I is current, and R is resistance, you can calculate the voltage drop across each component by multiplying the current through the component by its resistance.
If the two batteries in a circuit have different voltages, the total voltage in the circuit will be equal to the sum of the two individual battery voltages. However, the current may be different in each branch of the circuit, depending on the resistance of each branch. This can be calculated using Kirchhoff's Laws.
