The current in the electric stove circuit is 2.4 A. What electric charge passes through the cross-section in 4.2 s

The current in the electric stove circuit is 2.4 A. What electric charge passes through the cross-section in 4.2 seconds and what is the voltage at the terminals if 2200 J of work is done during this time?

I = 2.4 A.

t = 4.2 s.

A = 2200 J.

q -?

U -?

The strength of the current I is a physical quantity that shows what electric charge q passes through the cross-section of the conductor per unit of time t: I = q / t.

q = I * t.

q = 2.4 A * 4.2 s = 10.08 Cl.

According to the Joule-Lenz law, when an electric current passes through a conductor, work A is performed, the value of which is determined by the formula: A = U * I * t.

U = A / I * t.

U = 2200 J / 2.4 A * 4.2 s = 218 V.

Answer: an electric charge q = 10.08 C passes through the cross-section of the conductor, the voltage in the conductor was U = 218 V.
