An iron powered by a network voltage of 220 V. What charge passes through the heating element of the iron in 5 minutes, your resistance is 27.5 ohms.
Task data: U (mains voltage) = 220 V; t (duration of the iron) = 5 minutes (in SI t = 300 s); R (heating element resistance) = 27.5 ohms.
The charge that will pass through the heating element of the taken iron in 5 minutes is determined by the formula: q = I * t = (U / R) * t = U * t / R.
Let’s calculate: q = 220 * 300 / 27.5 = 2400 C or 2.4 kC.
Answer: A charge of 2.4 kC will pass through the heating element of the taken iron.
