(b) copper has low electrical resistivity The colonial government issued sheet-metal replacement roofs, but people couldn't sleep when tropical rains turned the tin roofs into drums. The length and radius of an electric resistance of a certain wire are doubled simultaneously, then the: Given three equal resistors, how many different combinations (taken all of them together) can be made? Considering 100mA as fatal current and 400 ohms as body resistance, the voltage may be calculated by this equation. Working principle of air blast circuit breaker. (c) same That said, the majority of the bodys resistance is in the skin - the dead, dry cells of the epidermis (the skins outer layer) are very poor conductors. When electrical energy of high voltage gets into the human skin, the resistance is reduced to 500 ohms. It also varies from person to person. None of this would prove anything about a harmful effect, but it would be somewhere to start. . material, eg copper, has lower resistance than steel. IB = 200/400 However the amount of resistance is different with dry and wet skin. IH= 0.05 Amp. (b) 60 W The resistance of the CAN bus terminal is usually 120 ohms.Two 60 ohm resistors are linked in series in the design, and there are usually two 120 ohm nodes on the bus.Basically, persons who are familiar with the CAN bus system.This is common knowledge. Solution: This problem is almost similar to above one. According to the Ohms Law, an ohm (1 ) is the value which has an electrical resistance when the electric circuit connected to a one volt (1 V) of voltage causes a current flow of one ampere (1A) . Tutorialspoint. The resistance of a human body is about: (a) 12 (b) 120 . Humans are conductors of electricity and have electrical resistance similar to any other material. (d) joule/coulomb/metre, Question 29. Supply Voltage (V) = 220 V. As we discussed in problem 1, RB and RH are connected in parallel, so 0.55 current will divided into two parts. You also have the option to opt-out of these cookies. (d) None of these, Question 35. 5 What is the highest voltage a human can withstand?

Which part of the human body offers the most electrical resistance? $(Neglect air resistance)$. Take the average debate on TV about the Iraq War (now with Syria and Iran) and it looks like, Should we bomb them now or later? The debate has been framed; excluded are the ideas of not bombing Iraq at all, or removing our military bases from all around the world, or diplomacy, or or or Same, too, it seems to me happens in the world of science. Yes, I know the standard response is that its such a small amount of electricity -- but a constant dripping of water on a rock will eventually wear a hole through it. The Current flow is obviously higher as the resistance goes down. (c) t = \(\frac{}{}\) As a physicist, I have to stick to my educated guess that there's no physical reason why touch screens would be dangerous. (c) 12 K May I can I measure the capacitance of a material? What is the potential difference across a hand-held fan that has a resistance of 120 and a current of 50 mA flowing through it? One way to do that would be to ask an assistant with a random number generatorto randomly present you with a real or "fake" touch screen (maybe a piece of glass made to look and feel identical, or maybe just the same touch screen turned off) many times, and see if you can reliably tell the difference between them (reliably = better than 50% with statistical significance). For dc and 50 Hz or 60 Hz ac currents, the human body can be approximated by a resistance. (a) H1 = H2 Not like existing styli. Resistance is measured in ohms. It looks like you can get one for about $70 (US) that will measure small enough capacitance.

Calculate Power, Current, Voltage or Resistance. But ask yourself this: "What would convince me that I'm wrong?". Human resistance is about 10,000 ohms on the high side and as little as 1,000 ohms if the person is wet. Does a person usually offer the most resistance to electricity? Taking Ohm's Law for voltage, current, and resistance, and expressing it in terms of current for a given voltage and resistance, we have this equation: The amount of current through a body is equal to the amount of voltage applied between two points on that body, divided by the electrical resistance offered by the body between those two points. current flow through human body (IH) is (a) 2 : 3 Don't use voltage from standard outlets. .. Would it need to be repeated by others? And before you say "buy one" When does an Ohm have an electrical resistance? (a) Joule I didn't know that. It is represented by the uppercase letter R.
