What work will a stationary electric field do in 30 minutes? creating a current strength of 2A on a section of a circuit with a resistance of 500 ohms.
Initial data: t (operating time of a stationary electric field) = 30 min (1800 s); I (current generated by the field) = 2 A; R (resistance of the circuit section) = 500 ohms.
The work that a stationary electric field will perform is determined by the formula: A = I ^ 2 * R * t.
Calculation: A = 2 ^ 2 * 500 * 1800 = 3600000 J (3.6 * 10 ^ 6 J; 3.6 MJ).
Answer: A stationary electric field will do the work of 3.6 MJ.
