Question

Problem (6) For the circuit diagrammed below, please (a) replace the 3.00 12,5.00 12, 2.00 12, 6.00 resistors with a single equivalent resistor, and state the value of the equivalent resistance. 20.0.2 2.002 120.0 V Please find 3.002 6.00 $2 60.0 V (b) the power supplied by the ideal 120.0 V source, 5.00 12 7.00 S2 (c) and the power dissipated by the 5.00 S2 resistor.

Answer 1

Also, = A. And 6) @ 2.2 and 6 are in series R,= (2+6) = 82 32 and 5-2 are in series, R2=(3+5)=82 R=bR AC 7o Rg8 h - parallel connection of R, and phy equivalent resistance is Reg F R, R2 8x8 848 Req= 4.2 Ang 3.ch امی 64-4-2 16 RIHR
