To find the voltage required to push a certain current through a resistor, you can use Ohm's Law, which is given by the formula:
\[ V = I \times R \]
where:
- \( V \) is the voltage,
- \( I \) is the current,
- \( R \) is the resistance.
Given:
- \( I = 20.0 \, \text{A} \)
- \( R = 120.0 \, \Omega \)
Now, substituting the values into the formula:
\[ V = 20.0 \, \text{A} \times 120.0 \, \Omega \]
\[ V = 2400.0 \, \text{V} \]
Therefore, the voltage required is **2,400 V**.
\[ V = I \times R \]
where:
- \( V \) is the voltage,
- \( I \) is the current,
- \( R \) is the resistance.
Given:
- \( I = 20.0 \, \text{A} \)
- \( R = 120.0 \, \Omega \)
Now, substituting the values into the formula:
\[ V = 20.0 \, \text{A} \times 120.0 \, \Omega \]
\[ V = 2400.0 \, \text{V} \]
Therefore, the voltage required is **2,400 V**.
