What is the current flowing through a lamp in a circuit with 12 volts of voltage and 4 ohms of resistance?
A. 3 Amps
B. 4 Amps
C. 6 Amps
D. 12 Amps
Answer:
The correct answer is B. 4 Amps.
When calculating the current flowing through a lamp in a circuit, you can use Ohm's Law which states: V = I * R, where V is the voltage, I is the current, and R is the resistance.
In this case, the voltage is 12 volts and the resistance is 4 ohms. By rearranging the formula, we get I = V / R. Plugging in the values, we get I = 12 / 4 = 3 Amps. Therefore, the current flowing through the lamp is 3 Amps.
It's important to understand the relationship between voltage, current, and resistance in an electrical circuit to make accurate calculations.
