Answer:
Explanation:
You didn't last any of the variables. You have to list the variables to tell which are which.
Voltage drop is a better measurement of resistance than testing static resistance because: current flow creates heat which adds to circuit resistance
The current flow or electric current is the measure of the electrons flow around a circuit. It is measured in amperes or "amps". If the current is higher the electrons flow is greater.
<h3>What is electricity?</h3>
Electricity or electrical energy is the energy that occurs due to the movement of electrons in the materials that are considered conductors.

Answer:
n = 4 x 10¹⁸ photons
Explanation:
First, we will calculate the energy of one photon in the radiation:

where,
E = Energy of one photon = ?
h = Plank's Constant = 6.625 x 10⁻³⁴ J.s
c = speed of light = 3 x 10⁸ m/s
λ = wavelength of radiation = 567 nm = 5.67 x 10⁻⁷ m
Therefore,

E = 3.505 x 10⁻¹⁹ J
Now, the number of photons to make up the total energy can be calculated as follows:

<u>n = 4 x 10¹⁸ photons</u>
