If a 6V battery is connected to a light bulb whose resistance is 55,000Ω How much current will flow in the circuit?
notka56 [123]

Answer:

Current, I = 0.000109 Amps

Explanation:

Given the following data;

Voltage = 6V

Resistance = 55,000 Ohms

To find the current flowing through the circuit;

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

V = IR

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

Making current the subject of formula, we have;

I = \frac {V}{R}

Substituting into the formula, we have;

I = \frac {6}{55000}

Current, I = 0.000109 Amps

DEFINITIONS

Approved - Acceptable to authority having jurisdiction. {California Electrical Code (CEC), Article 100}

Authority Having Jurisdiction – An organization, office, or individual responsible (i.e., LADBS

Electrical Testing Laboratory or Inspection) for enforcing the requirements of a code or standard, or

for approving equipment, material, an installation, or a procedure. (CEC, Article 100)

Equipment - A general term, including material, fittings, devices, appliances, luminaires, apparatus,

machinery, and the like used as part of, or in connection with, an electrical installation. (CEC, Article

100)

Identified - Recognizable as suitable for the specific purpose, function, use, environment, application,

and so forth, where described in particular code requirement. (CEC, Article 100)

Labeled - Equipment or material to which has been attached a label, symbol, or other accepted

identifying mark (i.e., embossed laboratory logo) of a recognized (approved) testing agency (see

definition) and concerned with product evaluation, that maintains periodic inspection of production of

labeled equipment or materials, and by whose labeling the manufacturer indicates compliance with

recognized national safety standards (see definition). (CEC, Article 100)

How much would a 75kg man weigh due to the effect of gravity
Nezavi [6.7K]

Answer: 735 N

Explanation:

Weight W is a measure of the gravitational force acting on an object and is directly proportional to the product of the mass m of the body by the acceleration of gravity g:  

W=m.g

In the case of our planet Earth, the acceleration due gravity is g=9.8 m/s^{2}. So for a man whose mass is m=75 kg, his weight is:

W=(75 kg)(9.8 m/s^{2})

W=735 N
