The open circuit terminal voltage of a source is 10V and its short circuit current is 4A.what will be the current when the source is connected to a linear resistor of resistance 2ohm?

    |dw:1442460624154:dw| V is the voltage of the voltage source, and R is the internal resistance. when on open circuit the voltage on the terminal will be equal to the voltage of the voltage source (V). When on short circuit, you can find the value of R since you know V and I. now connect the 2ohm resistor and again find the Current flowing with using V=IR

    A short circuit is equivalent to connecting a wire with no resistance between the positive and negative terminals of the voltage source.

    V = 10V I = 4A Use these knowns in V = IR in order to solve for R internal. Then add the internal resistance to the linear resistance. R Internal + R Linear = Total Resistance Then you can use V = IR again with the new resistance and the original voltage supply to solve for the current.
