Question

U=120B R=0,3мОм= I=?​

Answer 1

Ответ:

I=U/R=120/0,3=400 ампер

Answer 2

Ответ:

120/0,3=400 Ом

Объяснение:

По формуле Ома: l=U/R

Answer 3

To calculate the current (I) in a circuit, you can use Ohm's Law, which relates voltage (U), resistance (R), and current (I) with the formula:

I = U / R

In your case: U = 120 volts R = 0.3 milliohms (0.3 mΩ)

First, convert the resistance to ohms from milliohms:

0.3 milliohms = 0.0003 ohms (since 1 milliohm = 0.001 ohms)

Now, you can plug these values into the formula:

I = 120 V / 0.0003 ohms

I = 400,000 A

So, the current (I) in the circuit is 400,000 amperes, or 400 kA. Please note that this is an extremely high current, and such values are typically encountered in specialized industrial or research applications, not everyday household circuits.
