please help and explain those question thanks

Explain the difference between power and 2 , Why does connecting loads in parallel reduce the equivalent resistance of a circuit? 3 . On a holiday to Canada, a resident of England decides to bring his electric razor. He has heard that the plugs are different so he buys an adapter that will fit into an electric socket in Canada. When he plugs in and turns on his razor in Canada, it runs very slowly and is very weak. Explain why. The electric circuit to which a television set is connected is protected by a 15 A circuit breaker. If the power rating of the set is 450 W. how many 100 W light bulbs can be operated as well on this circuit without overloading the circuit breaker? The heating element of a stove operates at 240 V. How much electric energy is converted to heat if it takes 5.50 minutes to bring a pot of water to a boil? The element draws a current of 6.25 A. How much does it cost to run a 15.0 9 load for 12.0 minutes on a 125 V supply if the rate for electric energy is $0.0850/kWh
