Direct Current Circuits

Direct Current Circuits. A current is maintained in a closed circuit by an emf (electromotive force) Battery. An emf forces electrons to move against the electrostatic field in the source. It is the work done per unit charge in volts.

DC Circuits Quiz #1 Solution

DC Circuits Quiz #1 Solution. Mr. McCall. Find R T. Add series resistors together. R 1,2 = R 1 + R 2 = 20.0 ? + 1 4.0 ? = 34.0 ?. R 4,5 = R 4 + R 5 = 16.0 ? + 12.0 ? = 28.0 ?. Add parallel resistors together. 1/R 3-5 = 1/R 3 + 1/R 4-5 = 1/18.0 ? + 1/28.0 ? = 11.0 ?.
