Document Summary
Find all voltages and currents for the circuit shown. Perform kvl in both windows to check answers. Carry out answers to the 4th decimal point in engineering notation. Now it is possible to find the total current using ohms law (since we now have a series circuit) With the total current in hand, it is now possible to find the voltage across the two resistors (one of which is an equivalent resistance): Now, we expand the circuit back to the original form: We now can use a current divider to solve the next two currents (or kcl if you like): i1. Armed with these two currents we can now find the remaining voltages: 54 v rr r v roundoff e o. Example 1-7: find the total resistance and all i"s and v"s. First, the total resistance and total current must be found. The circuit must be collapsed starting with the branch farthest from the source voltage.
