calculation of appliances

[Somlembe]

Good day all,
Since am new in the forum well i have a question based on electrical appliances , if i have 10A breaker and need to connect 100watts lamps then how many should they be in order for them not to trip the breaker.and is there a maximum percentage for the load per breaker?

Many thanks

What voltage is your system working at?

Use the formulae for power based on voltage and current to work out your answer.

 

[Somlembe]

230v

 

[Sinbad]

Are you connecting in series or parallel?

 

[Somlembe]

parallel

 

[Sinbad]

So then, how many amps does each light bulb draw?

 

[Somlembe]

not sure but lets assume is 1.8amps

 

[Tabac]

P = A x V
V = I x R

 

[Sinbad]

not sure but lets assume is 1.8amps

How about we don't assume anything.

Work it out using the formula for power based on voltage and current.

you seem to be going about this the wrong way firstly, why on earth would you try to work out the maximum when you should rather be calculating your need?

 

[Tabac]

Just go to LED and connect 10.

Because he's trying to answer a homework question

Thanks for your contributions , i think i have enough idea as to what steps to follow from here

It's the formula right ? Works every time
