Rubber handgloves while working with electricity because rubber is an insulator and protects them from electric shocks (see Figure 20). Wood is also a good insulator. We are now in a position to answer thefollowing questions :Very Short Answer Type Questions1. Name the law which relates the current in a conductor to the potential difference across its ends.2. Name the unit of electrical resistance and give its symbol.3. Name the physical quantity whose unit is "ohm".Le4. What is the general name of the substances having infinitely high electrical resistance ?5. Keeping the resistance constant, the potential difference applied across the ends of a component is halvedBy how much does the current change ?6. State the factors on which the strength of electric current flowing in a given conductor depends.7. Which has less electrical resistance : a thin wire or a thick wire (of the same length and same material)?8. Keeping the potential difference constant, the resistance of a circuit is halved. By how much does the currentchange?9. A potential difference of 20 volts is applied across the ends of a resistance of 5 ohms. What current will flowin the resistance ?10. A resistance of 20 ohms has a current of 2 amperes flowing in it. What potential difference is there betweenits ends?11. A current of 5 amperes flows through a wire whose ends are at a potential difference of 3 volts. Calculatethe resistance of the wire.12. Fill in the following blank with a suitable word :Ohm's law states a relation between potential difference andort Answer Type Questions13. Distinguish between good conductors, resistors and insulators. Name two good conductors, two resistorsand two insulators.Classify the following into good conductors, resistors and insulators :​
