6. When using superposition, what is the ideal
internal resistance of a current source?
Short circuit
The source voltage divided by the source
resistance
The source voltage divided by the load
resistance
Infinite resistance
the source current through R1 is 6.34 mA. use current divider to determine how much current goes through R5 and R6
6 cells with 2 V emf and 0.1ohm internal resistance are connected in series. Four such sets are connected in parallel. The entire circuit is connected to a 9.85 ohm load. So find the load current, the current through each cell and the load voltage.
