Using the circut below to answer a through e a. Calculate the unloaded voltage at TP1. (S1 and S2 Open) b. Calculate the voltage at TP1 with S1 closed and S2 open. (load is applied) c. Calculate the loaded voltage at TP2 with S1 open and S2 closed. d. In the table below, circle the change of voltage that occurs at each test point when loads are applied to the unloaded voltage divider. (see paper) e. Circle the effect on current through R3 when S1 is closed, applying a load to the unloaded voltage divider. (see paper)
