1.	State whether the following statements are true or false. Correct the false statements:(1) The SI unit of charge is volt. (2) Voltmeter is always connected in series with the device. (3) The conventional direction of flow of current is from positive terminal to negative terminal. (4) Silver and copper are good conductors. (5) Resistivity of pure metals is more than alloys. (6) Resistance in series arrangement is used to decrease resistance of circuit. (7) A conducting wire offers less resistance to flow of electrons. (8) Charges are measured in ampere. (9) The unit of potential difference is ampere. (10) Resistance of a conductor is inversely proportional to the length of the conductor. (11) Ammeter is connected in parallel to the cell to measure current. (12) Fuse is made of wire having high melting point.
Answer» (1) False. The SI unit of charge is coulomb. (2) False. Voltmeter is ahvays connected in parallel with the device. (3) True (4) True (5) False. Resistivity of pure metals is less than alloys. (6) False. Resistance in series arrangement is used to increase resistance of circuit. (7) True (8) False. Charges are measured in coulomb. (9) False. The unit of potential difference is volt.
