A large lightning bolt is observed to have a 1.79×104A current that transfers 37.7C of charge. What was its duration, in milliseconds? Δt = ____ms

A circuit in a small appliance operates on a current of 1.5 mA. How many electrons enter and leave this part of the appliance in 5.0 s?

A 290-km-long high-voltage transmission line 2.0 cm in diameter carries a steady current of 1,150 A. If the conductor is copper with a free charge density of 8.5 1028 electrons per cubic meter, how many years does it take one electron to travel the full length of the cable? (Use 3.156 107 for the number of seconds in a year.)

Find the the current through the Galvometer (old version of Ammeter) in the following circuit. The resistance of the Galvometer is 2002.² R₁ R3 4Ω 392 G 20 V 192 6Ω R₂ R₁

In 2.9 s, 1.9 × 10¹9 electrons pass a certain point in a wire. What is the current I in the wire? 1= i

The quantity of charge through a conductor is modeled as Q = (3.00 mC/s^4)t^4 - (3.00 mC/s)t + 8.00 mC. What is the current (in A) at time t = 2.00 s?
