Tiga buah hambatan masing 200ohm 300ohm 400ohm tentukan hambatan penggantinya jika dirangkai secara a.seri b.pararel

A . Rs = R1+R2+R3
Rs = 200 + 300 + 400
Rs = 900 ohm

B. 1/Rp = 1/ R1 + 1/R2 + 1/R3
1/Rp = 1/200 + 1/300 + 1/400
1/Rp = (6+4+3)/1200
1/Rp = 13/1200
Rp = 1200/13 = 92,307 A

maaf kalo salah
