Answer

Equivalent Current Source for Voltage Source

In order to determine the equivalent current source for a voltage source with an internal resistance, we need to calculate the current that would flow through the circuit when the voltage source is replaced by a current source.

Given Parameters:
- Open Circuit Voltage (Voc) = 100V
- Internal Resistance (R) = 50Ω

Calculating Equivalent Current Source:
- The equivalent current source can be calculated using Ohm's Law: I = Voc / (Voc + R)
- Substituting the given values: I = 100 / (100 + 50) = 100 / 150 = 0.67A

Equivalent Current Source:
- Therefore, the equivalent current source for the given voltage source with an internal resistance of 50Ω is 0.67A.

Comparing with Options:
- Option 'a) 2A in parallel with 50Ω' is the correct equivalent current source, as the calculated value of 0.67A is in parallel with the internal resistance of 50Ω.

Conclusion:
- The equivalent current source for the given voltage source with an internal resistance of 50Ω is 0.67A in parallel with the internal resistance.
