With resistors, R 3 and R 4 reversed, the same current flows through the series combination and the voltage at point D, which is also the voltage drop across resistor, R 4 will be: V R4 = × 10Ω = 4 volts. Now with V R4 having 4 volts dropped across it, the voltage difference between points C and D will be 4 volts as: C = 8 volts and D = 4 volts. ...
