Answer:
The new current is half the original current.
Step-by-step explanation:
Ohm's Law:
We use Ohm's law to solve this question. It states that
In which is the voltage difference, R is the resistence, and I is the current.
A student builds a simple circuit with a single resistor with resistance R and measures an electric potential difference ΔV across the resistor.
So
The new current is half the original current.
Answer:
20 ft
Step-by-step explanation:
The two triangles in this problem are proportional to each other: so, the ratio between their height and the length of their base is equal for the two triangles.
Therefore, we can apply the rule of three, and we can write:
where:
H = 25 ft is the height of the large triangle
B = 10 ft is the length of the base of the large triangle
h is the height of the small triangle
B = 8 ft is the length of the base of the small triangle
And solving for h, we find:
