please solve all of them ihad no points yet i had to use it

Answer:
q.10 a. electric power is defined asquantity of charge passed in unit time at given potencial deferences in a conductor / circuit. it si unit is watt or joule / secound. p= vi
b. sorry i don't no
q.11 a. 1,000 jouls
one kilowatt- hour is equivalent to the enrgy of 1000 jouls used for 3,600 secounds or 3.6 million jouls in eqution form 1 kwh = 3.6 million j
b.1. one joule isdefined as the amount of energy exerted when a force of one newton is applied over a displacement of one meter.
2. 1 ohm is defined as the resitence of a conductor with a potential diference of 1 volt applied to the ends through which 1 ampere current flows.
3.one watt is defined as the energy consuption rate of one joule per secound 1 w= 1 j / 1 s one watt is also define the current flow of one ampere with voltage of one volt
4. one volt is defined as energy consumption of one joule per electrc charge of one columb .
thank you
