Flashlight has resistance of 2.4 what voltage is applied by the batteries if the current is 2.5a

Physics
1 answer:
Sergeeva-Olga [200]3 years ago
5 0

Answer:

6 voltage is applied by the batteries.

Explanation:

To solve this sort of problem involving current, resistance and voltage, we use the relation:<em> </em><em>Voltage</em><em>= </em><em>Current x Resistance</em>.

From the problem, the following have been given:

Resistance= 2.4 ohms.

Current= 2.5 amps.

Required: Voltage?

Fix the values of current and resistance into the relation:

Voltage= <em>2.5 x 2.4</em>

            =6 volts.

What quantities are related by Ohm's law? Check all that apply. voltage conductivity current resistance insulation
Free_Kalibri [48]

Answer: Current, resistance and voltage are the quantities which are related by Ohm's law.

Explanation:

A law which states that electric current is directly proportional to voltage and inversely proportional to resistance is called Ohm's law.

Mathematically, it is represented as follows.

I = \frac{V}{R}

where,

I = current

V = voltage

R = resistance

This means that the quantities related by Ohm's law include current, voltage and resistance.

Thus, we can conclude that current, resistance and voltage are the quantities which are related by Ohm's law.

To properly operate the laboratory thermometer Group of answer choices it needs to be shaken but make sure you have enough room
ruslelena [56]

Answer:

it needs to be shaken but make sure you have enough room to shake it safely

Explanation:

To properly operate the laboratory thermometer  it needs to be shaken but make sure you have enough room to shake it safely. This done because there is a small bend in the mercury channel of a clinical thermometer that uses mercury. You must shake the thermometer to get the mercury from a previous reading from the thermometer back into the bulb for taking new reading. The bend prevents flow back into the tube so that one can comfortably take reading.
