Hukum Ohm dan Kirchoff
Rangkaian ListrikSusunan beberapa komponen elektronik yang memiliki masukan (input) dan keluaran (output) berupa tegangan, dimana hubungan input-output nya tergantung bagaimana komponen-komponen elektronik tersebut disusun.

RANGKAIAN TRANSIEN
• ARUS KELUARAN BERUBAH SESUAI WAKTU
• BIASANYANYA BERHUBUNGAN DENGAN PENGISIAN DAN PENGOSONGAN KAPASITOR ATAU MENGGUNAKAN INDUKTOR

HUKUM OHM
CONTOH SOAL HUKUM OHM
• QuestionAn emf source of 6.0V is connected to a purely resistive lamp and a current of 2.0 amperes flows. All the wires are resistance-free. What is the resistance of the lamp?

CONTOH SOAL HUKUM OHM (lanjutan)
• Petunjuk:1. Where in the circuit does the gain in potential
energy occur? 2. Where in the circuit does the loss of potential
energy occur? 3. What is Ohm's Law?
CONTOH SOAL HUKUM OHM (lanjutan)
Solusi• The gain of potential energy occurs as a charge
passes through the battery, that is, it gains a potential of =6.0V. No energy is lost to the wires, since they are assumed to be resistance-free. By conservation of energy, the potential that was gained (i.e. =V=6.0V) must be lost in the resistor. So, by Ohm's Law:
• V = I R• R=V/I• R = 3.0 W
