When does a lightbulb carry more current, (a) immediately after it is turned on and the glow of the metal filament is increasing
emmasim [6.3K]

A  lightbulb carries more current immediately after it is turned on and the glow of the metal filament is increasing; option A.

<h3>What is current?</h3>

Current refers to the flow of electric charges typically electrons.

Current flowing through a metallic material decreases with increase in temperature of the material.

This is because the resistance of the metal increases with increase in temperature.

Therefore, for a light bulb, the current flow through it will be maximum when it is just turned on because the temperature, and hence the resistance of the  filament is at its lowest.

In conclusion, current flow decreases with increase in resistance.

When reading a digital volt-ohmmeter (DVOM), you have a reading of 2168 mV, which is the same as:__________
levacccp [35]

Answer:

D, both A and B

Explanation:

2168 mV is the SI unit for potential difference and the Voltmeter.

The primary unit is Volt, represented as V. Due to the fact that there can be a much higher reading, or an even much more smaller one, comes the need for variants of the same unit.

10^-3 is called milli and represented as m

10^3 is called killo and represented as k

10^-6 is called micro and represented as µ

10^6 is called mega and represented as M

and even much higher variants of up to 10^12 and 10^-12

As we can see from the aforementioned example, 10^-3 is milli and represented as m

And our question gave us the unit in mV, which stands for millivolts.

Also, if we look at option B, it states, 2.168 volts. This 2.168 volts is also the same thing as A. Take a look at it this way, I said mV is 10^-3, right?

So, 2168*10^-3 is also 2168/100 which is 2.168. The only difference here is, once we make this conversion from mV, we have to drop the milli tag, because we have already made a conversion, and thus, leave it as V.

2168 mV = 2.168V

Hence why we picked option D, Both A & B as the right one

Only the masses of the objects and the distance between them. Nothing else affects the gravitational forces. Not even a concrete, steel, and Kryptonite wall between them.
