Answer:
<h3>
This shows that the power dissipated by the circuit element is four times its original power if the current is doubled.</h3>
Explanation:
The formula for calculating the power expended in a circuit is P = I²R... 1
i is the current (in amperes)
R is the resistance (in ohms)
If a circuit element maintains a constant resistance and the current through the circuit element is doubled, then new current I₂ = 2I
New power dissipated P₂ = (I₂)²R
P₂ = (2I)²R
P₂ = 4I²R ... 2
Dividing equation 2 by 1 will give;
P₂/P = 4I²R/I²R
P₂/P = 4
P₂ = 4P
This shows that the power dissipated by the circuit element is four times its original power if the current is doubled.
Answer:
the heat of the light.
Explanation:
no matter the light, there's always heat being produced from it. and heat makes liuqid rise
Well, if you can't experiment safely, why experiment at all? I believe it's D because of that.
