Fizik Örnek Sorular

1-) [Devre şeması: $14\Omega$ seri, ($12\Omega$ // $12\Omega$ // $12\Omega$) ve ($6\Omega$ // $3\Omega$)].

a- $R_{es} = ?$

b- $i = ?$

$V = i \cdot R$

2-) [Devre şeması: $12\Omega$ seri, ($15\Omega$ // $15\Omega$ // $15\Omega$) ve $3\Omega$ seri; $V=30$ volt].

a- $R_{es} = 12 + 5 + 3 = 20\Omega$

b- $i = ?$

$V = i \cdot R \Rightarrow 30 = i \cdot 20 \Rightarrow i = \frac{3}{2} A$

3-) [Potansiyel-Akım Grafiği]. K noktası için $V=30$ volt ve $i=10$ Amper.

$V = i \cdot R \Rightarrow 30 = 10 \cdot R \Rightarrow R = 3\Omega$.

Altındaki devrede $V=9$ volt ise $i$ kaçtır?

$V = i \cdot R \Rightarrow 9 = i \cdot 3 \Rightarrow i = 3A$

Soruda görsel içerik var: The image contains handwritten physics problems on squared paper. Problem 1: A circuit diagram with a $14\Omega$ resistor in series with a parallel combination of $12\Omega$, $12\Omega$, and $12\Omega$, followed by another parallel combination of $6\Omega$ and $3\Omega$. An ammeter shows $2A$. Problem 2: A circuit with a $12\Omega$ resistor in series with three parallel $15\Omega$ resistors and another $3\Omega$ resistor. The voltage source is $30V$. Problem 3: A potential-current graph (V-I) shows a linear relationship passing through $(10A, 30V)$ labeled 'K'. Below it, a simple circuit with a $9V$ source and an unknown ammeter reading.
