Question

How much voltage gives 5 amps of current through a 3 Ω light bulb?

a) V = 15 V

b) V = 10 V

c) V = 8 V

d) V = 5 V

Answer 1

Using Ohm's Law (V = I × R), 5 amps of current through a 3 Ω resistor would result in 15 volts. Therefore, the correct answer is 15 volts.

Step-by-step explanation:

To find out how much voltage gives 5 amps of current through a 3 Ω light bulb, we can use Ohm's Law. Ohm's Law states that Voltage (V) is equal to the current (I) flowing through a resistor multiplied by the resistance (R) of the resistor. The formula is V = I × R. In this case, the given current (I) is 5 amps and the resistance (R) of the light bulb is 3 Ω. Applying Ohm's Law: V = 5 amps × 3 Ω = 15 volts. Therefore, 5 amps of current through a 3 Ω light bulb would give a voltage of 15 volts. Hence, the correct answer is a) V = 15 V.
