## anonymous one year ago When a 20 V battery is hooked up to a 10 Ω resistor in a circuit, how much current flows through the circuit? A. 0.5 A B. 2 A C. 20 A D. 200 A

1. Michele_Laino

we have to apply the Ohm's law, namely: $I = \frac{{\Delta V}}{R}$

ok! 20/10? solution is 2 A? choice B? :/

3. Michele_Laino

correct!
