Question

What is the difference between DC circuits and AC circuits? Select One of the Following: DC is carried by electrons; AC by protons. DC is carried by protons; AC by electrons. DC is the flow of positive charge; AC the flow of negative charge. DC is produced by electric fields; AC by magnetic fields. DC does not change direction; AC does. Analyze the circuit to the right with Delta V_1 = 12 V, Delta V_2 = 6 V, R_1 = R_2 = R_3 = 10 Ohm. Use the directions for the currents drawn on the diagram. Write the loop equation for the loop drawn on the diagram. Select One of the Following: Delta V_1 + I_3 R_1 - Delta V_2 - I_3R_2 = 0 Delta V_1 - I_3R_1 + Delta V_2 + I_3R_2 = 0

Explanation / Answer

(14.7) Answer is (e) DC does not change the direction but AC does.

(14.8) Answer is (e)
because in large loop according to kirchoff's voltage law the voltage across R3 is not take part is we write voltage law equation for both small loops here the voltage acoss R3 should be mentioned.
