This video will definitely give you the clear answers for below questions... Example 12.1/Example 11.1 [1 Mark] A current of 0.5 A is drawn by a filament of an electric bulb for 10 minutes. Find the amount of electric charge that flows through the circuit. Example 12.2/Example 11.2 [1 Mark] How much work is done in moving a charge of 2 C across two points having a potential difference 12 V? Example 12.3/Example 11.3 [2 Mark] (a) How much current will an electric bulb draw from a 220 V source, if the resistance of the bulb filament is 1200 Ω? (b) How much current will an electric heater coil draw from a 220 V source, if the resistance of the heater coil is 100 Ω? Example 12.4/Example 11.4 [1 Mark] The potential difference between the terminals of an electric heater is 60 V when it draws a current of 4 A from the source. What current will the heater draw if the potential difference is increased to 120 V? Example 12.5/Example 11.5 [3 Mark] Resistance of a metal wire of length 1 m is 26 Ω at 20°C. If the diameter of the wire is 0.3 mm, what will be the resistivity of the metal at that temperature? Using Table 12.2 OR 11.2, predict the material of the wire. Example 12.6/Example 11.6 [2 Mark] A wire of given material having length l and area of cross-section A has a resistance of 4 Ω. What would be the resistance of another wire of the same material having length l/2 and area of cross-section 2A? For doubts: Please send your queries to 9663873649 and get it cleared.
