Question

T=20c A=120kDж U=12B I=?

Answer 1

A=I*U*t

I=A/(U*t)=120*10^3/(12*20)=500 A

Answer 2

To calculate the value of I (current), we need to use Ohm's law, which states that the current flowing through a conductor is equal to the voltage across the conductor divided by its resistance. The formula is:

I = U / R

where: I = Current (in Amperes) U = Voltage (in Volts) R = Resistance (in Ohms)

However, in the information you provided, you didn't specify the resistance (R) value. Without the resistance, we cannot determine the current (I) using Ohm's law.

Please provide the value of the resistance (R), and I'll be able to calculate the current for you.
