i Are resistors 3 and 4 in series?

ii. Are resistors 1 and 2 in series

iii. Is the battery in series with any resistor?

iv. What is the potential drop across the resistor 3?

A uniform wire of resistance 100 Ω melted and recast into wire of length doubles that of the original. What would be the resistance of the new wire formed?

A house has 3 tube lights, two fans and a Television. Each tube light draws 40W. The fan draws 80W and the Television draws 60W. On the average, all the tube lights are kept on for five hours, two fans for 12 hours and the television for five hours every day. Find the cost of electric energy used in 30 days at the rate of Rs. 3.00 per Kwh.
