Question

7 Find The total resistances of 62 42 R,=? ( a ) 52 122 582 An (6) 9 62 ir b Rab=?

Answer 1

Ro RI Ry Կ. S-2 1212 R3 # R22 Rg are in parallel 8 - 12 + 1 2 3 1 LUI R2 R! ER 6 12 2+1 12 - 3 72 =) R=4 R3 Nav Ry, R and Ry are in series Ry+R'+ Ry = 5+4+4=1312 R = Rrotel Riotal =13.12 Ri R4 (6) an suz & 862 Rose R2 bem 42 HA - Rug Roi Rs are in series 80 R = Ruths the = 6+5+11 R = 222 RI & ka Teacher's signature

Rz and R are in parallel, so de + 5 => R=4.711 20 2 T R RL t R3 D R1 - a 25 Nav Ry, R2 and R are ER" in series so bo Rotal = R1+R2+R'=5+4+4.71 R Total = 13.712 30
