If you connected 10 of these 12V (10 W) lamps in parallel, to the 12V source, how much current would the source have to supply

Flauer [41]

Answer:

$T=8.33A$

Explanation:

From the question we are told that:

Number of battery $n=10$

Voltage source $E=12V$

Lamp Power $P=10W$

Generally the equation for Resistance is mathematically given by

$R=\frac{V^2}{P}$

$R=\frac{12^2}{10}$

$R=14.4ohms$

Therefore

$R_{eq}=\frac{14.4}{10}$

$R_{eq}=1.44$

Generally the equation for Current is mathematically given by

$T=\ffrac{V}{Req}$

$T=\frac{12}{1.44}$

$T=8.33A$

S= 343m/s
F=256Hz

WL= 343ms/256-1
WL=V/F

= 1.339844m

Two north magnets will do this

DerKrebs [107]

Answer:

Repel one another

Explanation

I am assuming you meant "two north poles will do this" Or something similar.

because you can't isolate poles, so a magnet wouldn't be just north

ANYWAYS i say repel because like terms repel, opposites attract.
