A light bulb has 240 Ω of resistance when connected to a 120 V electrical socket. What is the current through the light bulb? (AKS 8b) Question 36 options:

2.0 A

1.0 A

0.50 A

0.20 A

0.50 A

Explanation:

We can find the current from this through Ohm's Law:

V = IR

Now, in it's original form, we're only looking for Voltage. However, we can switch this formula around to find each part of it:

I = V / R (current)

R = V / I (resistance)

In this case, we'll use the formula for current:

V = 120 V

R = 240 Ω

I = ?

I = 120 / 240

I = 0.5 A

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
