A flashlight has a resistance of 30 Q and is connected
by a wire to a 90 V source of voltage. What is the
current in the flashlight?

3 A

Explanation:

The relationship between voltage, current and resistance in a conductor is expressed by Ohm's law, which states that:

where:

V is the potential difference across the conductor

R is the resistance of the conductor

I is the current flowing through it

In this problem, for this flashlight we have:

V = 90 V is the potential difference

is the resistance of the flashlight

Solving for I, we find the current:

pretty sure it's false
