Which one of the following materials is likely to exhibit more conductive properties than insulating properties?

Which one of the following materials is likely to exhibit more conductive properties than insulating properties? Correct Answer Wet skin

Wet skin is good conductor of electricity. This is because:

  • About 70% of the body is made up of water and various ions such as  Na+, K+, Cl-  are present in the water. 
  • Salt water provides a large surface area of contact for the conductive element and it connects with the sweat glands so electricity can flow past the skin and into your body.
  • Thus the resistance of wet skin is becomes low and is about 1000 Ω and so current can pass at greater rate for wet skin as compared to dry one.

The question given below consists of a statement, followed by three arguments I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: India's burgeoning shadow finance sector is likely to face a shake-up after defaults at one major lender battered the nation's financial markets in the past week and reinforced worries about credit risk. Industry officials and experts say they expect Indian regulators to cancel the licences of as many as 1,500 smaller non-banking finance companies because they don't have adequate capital, and to also make it more difficult for new applicants to get approval. Which of the following argument(s) stated support(s) the given fact? Arguments: I. Better capitalised and more conservatively run finance firms are likely to swallow up an increasing number of smaller rivals. That could make it difficult for many small borrowers to get loans, especially in the countryside where two-thirds of India's 1.3 billion people live and put the brakes on a surge in private consumption with a knock-on effect on growth.  II. The shadow banking sector now comprises more than 11,400 firms with a combined balance-sheet worth 22.1 trillion rupees ($304 billion) and is less strictly regulated than banks. It has been attracting new investors, particularly as the nation's banks have had to slow their lending as they seek to work through $150 billion of stressed assets.  III. Nearly 11,000 of India's NBFCs are small and medium-sized businesses with an asset base of less than 5 billion rupees. But the top 400, many of which are backed by banks and finance companies, control about 90 percent of the assets under management.
