His displacement is 0 .hope this helps :)
<u>Answer</u>
<span>C. It will move back and forth between a large positive and a large negative value.</span>
<u>Explanation</u>
The generator in the diagram produces an alternating current. This means the direction of the current every time the generator rotates. The current produced is large.
The needle will move back and forth in every rotation.
Answer:
Correct answer: Ic₂ = 48 mA = 48 · 10⁻³ A
Explanation:
Given:
U₁ = 12 V DC first battery voltage
Ic₁ = 24 mA = 24 · 10⁻³ A Intensity of current with the first battery
U₂ = 24 V DC second battery voltage
Ic₂ = ? Intensity of current with the second battery
The formula that applies to a simple electric circuit under the Ohm's law is:
R = U / Ic
where R is the total resistance in the electrical circuit and it is constant.
R = U₁ / Ic₁ = U₂ / Ic₂ ⇒ U₁ / Ic₁ = U₂ / Ic₂ ⇒ Ic₂ = (U₂ · Ic₁) / U₁
Ic₂ = (24 · 24) / 12 = 48 mA
Ic₂ = 48 mA = 48 · 10⁻³ A
