To calculate the current through R1, you can use Ohm's Law (I = V/R) where I is the current, V is the voltage, and R is the resistance. In a parallel circuit, the total current is divided among the branches, so the current through R1 can be found by taking the total current (4.06A) and dividing it by the resistance of R1.
The total current in a parallel circuit is the sum of the individual branch currents. In other words, it is the current that flows into the circuit at the source and then splits into multiple paths, with each path carrying a portion of the total current.
To find the resistance of R1, you can rearrange Ohm's Law to solve for R. This means dividing the voltage by the current (R = V/I). You can use the voltage and current values for R1 to calculate its resistance in the circuit.
When you add another resistor in parallel, the total resistance of the circuit decreases. This means that more current will flow through the circuit, resulting in an increase in the total current. However, the current through each individual branch will stay the same.
Yes, you can use Kirchhoff's Laws (specifically Kirchhoff's Current Law) to solve for the current in a parallel circuit. This law states that the sum of all currents entering a junction must equal the sum of all currents leaving the junction. By applying this law to each junction in the parallel circuit, you can solve for the current through each branch.
