A circuit contains three resistors connected in series. The value of R1 is 200 ohms the value of R2 is 640 ohms and the value of R3 is 500 ohms . the circuit is supplied with 6 VDC. what is the total voltage drop across the three resistors?
If the there are no other elements in the circuit in addition to the three resistors, then the total voltage of the power supply appears across the resistors ... 6 volts.
