Which one of the following does not affect the electrical resistance of a body?
The color of the body does not affect its electrical resistance. Electrical resistance is determined by factors such as the material, dimensions, and temperature of the body. The color of an object is related to its appearance and does not have a direct impact on its electrical properties.
How does the size of the wire affect the electrical resistance?
The size of the wire directly affects the electrical resistance. Thicker wires have lower resistance compared to thinner wires, as there is more space for electrons to flow through, reducing the resistance. Conversely, thinner wires have higher resistance due to smaller pathways for electron movement.
Why does heating a metal wire affect its electrical resistance?
Heating a metal wire affects its electrical resistance because as the wire heats up, the atoms within the wire vibrate more vigorously, causing more collisions with the electrons flowing through the wire. This increased collision rate hinders the flow of electrons, leading to a higher resistance in the wire.
What are the units of resistance in an electrical circuit measured in?
The units of resistance in an electrical circuit are measured in ohms ().
Do bends in a wire affects its electrical resistance?
Unless the wire is broken, a bent wire should still be able to conduct electricity as well as a straight one.

What is the electrical resistance for a dry body?
low
Does material composing the body effect the electrical resistance of a body?
Yes.

What part of the human body has the highest resistance to electrical current?
The Skin
Disease that affects one of the body systems?
Type 2 diabetes affects the endocrine system by causing insulin resistance.
How does wetness affect the resistance of your body?
When your body is wet, the water on your skin can decrease the resistance of your skin, making it easier for electricity to pass through your body. This can increase the risk of electrical shock or injury when coming into contact with electricity. It is important to stay dry when working around electrical sources to minimize this risk.
Electrical shock to the body affects the?
Electrical shock affects the nervous system as the electrical current disrupts the normal functioning of nerves and muscles in the body. It can cause muscle contractions, burns, and potentially disrupt the heart's rhythm, leading to serious injury or death. Immediate medical attention is crucial in such cases.
What are the four factorws affecting electrical resistance?
There are really only three things that affect electrical resistance. They are the length and cross-sectional area of a conductor and its resistivity. However, resistivity depends not only on the material from which the conductor is manufactured, but upon its temperature. So you could say that temperature indirectly affects resistance via its resistivity.
The following does not affect the electrical resistance of a body?
The electrical resistance of a body is primarily influenced by factors such as material type, length, cross-sectional area, and temperature. However, external factors like the body's shape or surface texture, as long as they don't change the physical dimensions or material properties, generally do not affect resistance. Additionally, environmental conditions like humidity may influence resistance in some materials but are not a direct factor of the body's intrinsic properties.
What measures electrical resistance?
an ohm meter OR multimeter is used to measure the electrical resistance...
How much resistance do your body have?
You can not find a set amount of electrical resistance because your body is made of many different materials and the amount varies with time ex: your body may, hypothetically, conduct more current if it is better hydrated
