Sebuah mikrofon 4 ohm dipasang pada tegangan 12 volt. Arus yang mengalir pada mikrofon adalah…
1/3 A
1/2 A
3 A
48 A
Answer explanation
The correct answer is 3 A because according to Ohm's Law (V = I * R), the current (I) flowing through the microphone is equal to the voltage (V) divided by the resistance (R), which is 12 V / 4 ohm = 3 A.
