The current in the electric hotplate circuit is 1.4 A. What electric charge passes through the cross section of its spiral in 20 minutes?
These tasks: I (current in the circuit of the electric hotplate used) = 1.4 A; t (duration of tile operation) = 20 min (in SI t = 1200 s).
To calculate the passed electric charge, you must use the formula: q = I * t.
Calculation: q = 1.4 * 1200 = 1680 C (1.68 kC).
Answer: a charge of 1680 C passed through the spiral of the electric hotplate in 20 minutes.
