Final answer:
To find the Thevenin voltage (Vth) and Thevenin resistance (Rth) in a circuit with a 5 amp current source, remove the load and calculate Vth as the open-circuit voltage, then deactivate all sources to find Rth as the equivalent resistance from the load's perspective.
Step-by-step explanation:
In finding the Thevenin voltage (Vth) and Thevenin resistance (Rth) for a circuit with a 5 amp current source, you need to use a systematic approach. First, you want to remove the load from the circuit and then identify and analyze the open-circuit voltage and the resistance seen from the load's perspective. To find the open-circuit voltage, which is the Thevenin voltage, you would calculate the voltage across the open terminal where the load was connected using methods such as voltage division or nodal analysis.
Once the Thevenin voltage is known, you calculate the Thevenin resistance by deactivating all independent voltage sources and replacing them with a wire (short circuit), deactivating all independent current sources by replacing them with an open circuit, and then finding the equivalent resistance seen from the terminals.
The question references a specific current flow and mentions Ohm's law, which relates current (I), voltage (V), and resistance (R); the changes in the terminal voltage due to current changes, which can be used to calculate internal resistance; and conservation of charge, which states that the total current coming from a source is the sum of the individual currents through resistors in parallel.
