19-1 Resistors in Series and Parallel • Series Circuits • Current is constant in a series circuit. • Resistors in series are added… • Req=R1 + R2 + R3 • V=V1 + V2 + V3=IR1 + IR2 + IR3 • V=IReq
Parallel Circuits • I=I1 + I2 + I3 • Voltage is constant in a parallel circuit. • 1/Req=1/R1 + 1/R2 + 1/R3…. • See diagrams page 555-558 • See Example 19-1 and 19-2 p558 • See Example 19-3 and 19-4 p560 and Example 19-6 p561
HOMEWORK • P581 PR# 1-7 and 15 due Thurs. BOP
