2. Peter wants to use a glass rod as an insulator. The rod's diameter is 12mm and its resistivity at 20°C is 1.0 x 100 m. How long (mm) must the rod be to offer a resistance of 8.2 x 1000? 3. A lamp draws a current of 0.6 ampere when it is connected to a 220-volt source. What is the resistance and power rating of the lamp? 4. A bulb is connected across a 120-volt source. It consumed 0.015 Kw.hr of energy in just 30 minutes. a. How much current is present? b. What is the resistance of the bulb?
