Question

A 1.5V battery is connected to a small light bulb with a resistance of 3.5 what is the current in the bulb?

Answer 1

The current in the bulb is approximately 0.43A.

Step-by-step explanation:

The current in the bulb can be found using Ohm's Law, which states that current is equal to voltage divided by resistance.

Using the given values:

Voltage (V) = 1.5V

Resistance (R) = 3.5 ohms

Current (I) = Voltage (V) / Resistance (R)

Substituting the values, we have:

I = 1.5V / 3.5 ohms = 0.43 A

Therefore, the current in the bulb is approximately 0.43A.

Answer 2

Technically, we don't have the information needed to calculate the current,
because you haven't mentioned the units of the 3.5 .

Since the 3.5 is a resistance, we strongly suspect ... and we'll therefore
assume ... that the 3.5 has the units of ohms. Then . . .

Current = (voltage) / (resistance) = (1.5/3.5) = 3/7 of an Ampere.

(429 mA, rounded)
