N) What is the power of the battery E2? Express your answer to two significant digits and include the appropriate units. Enter positive value if energy is used by the battery and negative value if energy is supplied by the battery.
Explanation / Answer
(a) i1= (E1-E2)/R
i1= (10-5)/40
i1=0.125 A
(b) V1= i1 R
V1= 0.125(40)
V1=5 volts
(c)i2= 5/(40+40+40)
i2=0.042 A
(d) v2=i2 R2
V2= 0.042(40)
V2=1.67 Volts
