Question

Need some help with this problem. I realize the sketch is difficult to show on a computer so dont worry too much about that.

Three resistors of 20 ohms, 40 ohms & 80 ohms are connected in a SERIES closed curcuit with a 70 Volt source. {assume ideal curcuit}...

a) Make a sketch of this circuit ( include correct schematic diagrams for ALL components...

b) Determine the current through the curcuit:...

c)Determine the voltage drop across each resistor:...

d) Determine the power dissapated by the circuit:...

Explanation / Answer

a

b)Req=140 ohm

I=70/140=0.5 A

C) V20=IR=10V

V40=IR=20V

V80=IR=40 V

D=P=I^2Req

P=35 W
