Question

A group is protected by a 10A fuse. The following appliances are connected in the group:
- a 2350W hot plate
- a 600W spinner
- a 950W vacuum cleaner
Calculate the current through the group

Answer 1

wts the potential difference?

Answer 2

It doesnt say :(

Answer 3

resistance?

Answer 4

Nope :/

Answer 5

i think either resistance or potential difference hv to given to calculate current

Answer 6

I know that's what I thought too, but there's nothing in the book

Answer 7

Wait I think I've got it

Answer 8

The potential difference is 230V

Answer 9

totsl power
p=2350+600+950Watt=?

Answer 10

total

Answer 11

3850 W

Answer 12

the formula is
p=vi

Answer 13

But you can't divide P by v right?

Answer 14

why not

Answer 15

Because to get i you have to: u/r=i

Answer 16

i=p/v

Answer 17

i think u r telling abt ohms law

Answer 18

v=ir

Answer 19

Oh, right so then the anwer is 16.74?

Answer 20

bt i m telling abt
p=vi

Answer 21

ya u r right

Answer 22

Okay, thankyouuu ^^

Answer 23
