How great is the work when moving a charge equal to 500 C in an electric stove connected to the network with a voltage of 220 V?
Q = 500 Cl.
U = 220 V.
A -?
When an electric current passes through a conductor, it performs work A, the value of which is determined by the Joule-Lenz law: A = I * U * t, where I is the current strength, U is the voltage at the ends of the conductor, t is the time the current passes through the conductor.
According to the definition, the current strength I is the ratio of the electric charge Q passed through the cross-section to the time of its passage t: I = Q / t.
Work when moving an electric charge A will take the form: A = Q * U.
A = 500 Cl * 220 V = 110,000 J.
Answer: when moving an electric charge in an electric stove, work A = 110,000 J.
