Question

please answer the following questions: 1) calculate the resistance of a heater rating 600 W -120 V. 2) a 220 V -100 W bulb is connected to a 110 V source. calculate the power consumed by the bulb 3) an electric iron consume energy at the rate of 800 W .if mains voltage be 200 V . calculate the current flowing and the resistance of the iron. 4) 1000 J of heat are produced each second in a 2.5 ohm resistance . find the potential difference across the resistor . 5) how much work is done in moving a charge of 3 C across two points having a potential difference 15 V? 6) 6 J of work is done in moving a positive charge of 3 C between two points. find the potential difference between the points
