In a parallel circuit, the total current is equal to the sum of the individual branch currents. This means that you can find the total current by adding up the currents in each branch of the circuit.
To find the equivalent resistance in a parallel circuit, you can use the formula: 1/Req = 1/R1 + 1/R2 + 1/R3 + ... + 1/Rn, where Req is the equivalent resistance and R1, R2, R3, etc. are the individual resistances in each branch. Once you have this value, you can use Ohm's Law (V = IR) to find the current in the circuit.
Yes, the equivalent resistance in a parallel circuit can be lower than the individual resistances. This is because in a parallel circuit, the total current is divided between the branches, which means that the individual resistances are experiencing less current than if they were in a series circuit. This results in a lower equivalent resistance.
The more branches there are in a parallel circuit, the lower the equivalent resistance will be. This is because adding more branches creates more paths for the current to flow through, reducing the overall resistance in the circuit. As a result, the equivalent resistance decreases as the number of branches increases in a parallel circuit.
To calculate the current in each branch of a parallel circuit, you can use Ohm's Law (V = IR) along with the total current and the individual resistances in each branch. Simply rearrange the formula to solve for the current (I = V/R) and plug in the appropriate values for each branch to find the current in that specific branch.
