Answer 1

To calculate the value of equivalent resistance, total current in the circuit, and potential difference between points A and B in the given electrical circuit, you need to apply the relevant formulas and principles from Ohm's law and circuit analysis.

Step-by-step explanation:

To calculate the value of (a) equivalent resistance, (b) total current in the circuit, and (c) potential difference between points A and B in the given electrical circuit, you need to apply the relevant formulas and principles from Ohm's law and circuit analysis.

1. Equivalent resistance: In this circuit, the resistors are connected in series and parallel. To find the equivalent resistance, you need to simplify the circuit by combining the resistors using the appropriate formulas. Start by finding the equivalent resistance of the resistors in series, and then find the equivalent resistance of the parallel resistors using the appropriate formulas.
2. Total current: Once you have found the equivalent resistance, you can use Ohm's law (V = I × R) to calculate the total current flowing through the circuit. Substitute the equivalent resistance and the potential difference provided in the circuit into the formula to solve for the total current.
3. Potential difference: To find the potential difference between points A and B, you can use Ohm's law again. Select any resistor that connects points A and B, and use the formula V = I × R, where V is the potential difference, I is the total current, and R is the resistance of the selected resistor.

Answer 2

Step-by-step explanation:

To calculate the values in the given electrical circuit, we need more information such as the resistances of the individual components and the potential difference (voltage) applied across the circuit. Without this information, it is not possible to determine the values of the equivalent resistance, total current, and potential difference between points A and B.

In electrical circuits, the equivalent resistance can be calculated using different methods depending on the circuit's configuration, such as series or parallel. The total current can be determined using Ohm's Law (I = V/R), where I is the current, V is the voltage, and R is the resistance. The potential difference between two points in a circuit can also be calculated using Ohm's Law (V = IR), where V is the potential difference, I is the current, and R is the resistance.

To accurately calculate these values, we need more information about the resistances and voltage in the circuit. Once we have that information, we can apply the appropriate formulas and calculations to determine the values of equivalent resistance, total current, and potential difference between points A and B.
