- If 3.0 x 10-5 electrons flow through a section of a wire of diameter 2.0 mm in 2.0 s, what is the current in the wire? O 7.5 x 107 A 0.12 mA O 0.24 mA O 7.5 x 1014 A hoTwo resistors with values of 44 Ω and 16 Ω, respectively, are connected in series and hooked to a 12 V battery. (a) How much current is in the circuit? A(b) How much power is expended in the circuit? WYour car battery is dead, and your friends are helping you start your car with cheap jumper cables. One cable carries current from their car to your car, and a second cable returns that current to their car. As you try to start your car, a current of 80.0 A flows through the cables to your car and back, and a voltage drop of 6.00 V appears across each cable. If you replace the cheap cables with cables having half their electric resistance, what voltage drop will appear across each new cable if the current doesn't change? AV= i
