Hukum ohm, bantu jawab ngab​

nomor 1

diket:

I = 2 A

V = 18 V

ditanya:

R…..?

jawab:

R = V / I

R = 18 volt / 2 A

R = 9 ohm

Jadi, besar hambatannya adl 9 ohm.

nomor 2

diket:

R1 = 5 ohm

R2 = 6 ohm

R3 = 2 ohm

dipasang seri

ditanya:

hambatan total (Rs)….?

jawab:

Rs = R1 + R2 + R3

Rs = 5 ohm + 6 ohm + 2 ohm

Rs = 13 ohm

Jadi, besar hambatan penggantinya adl 13 ohm.

nomor 3

diket:

R1 = 6 ohm

R2 = 12 ohm

dipasang paralel

ditanya:

hambatan pengganti (Rp)…?

jawab:

1 /Rp = 1/R1 + 1/R2

1/Rp = 1/6 + 1/12

1/Rp = 2/12 + 1/12

1/Rp = 3/12

Rp = 12/3

Rp = 4 ohm

Jadi, besar hambatan penggantinya adl 4 ohm.
