All four configurations would produce an electric current, but the effectiveness depends on the specific conditions and setup. Here's a breakdown of each option:
A. **Rotate a coil of copper wire between two magnets**: This configuration uses electromagnetic induction, which can generate an electric current when the coil moves within the magnetic field.
B. **Connect a wire between a copper and zinc strip sitting in a beaker of water**: This setup can form a simple galvanic cell if there are ions in the water. The difference in reactivity between the copper and zinc can produce a flow of electrons, resulting in an electric current.
C. **Connect a wire to the (+) positive end of a battery and the other end to a light bulb**: This configuration will produce an electric current, as batteries provide a potential difference (voltage) that drives current through the circuit.
D. **Connect a wire to the (-) negative end of a battery and the other end to a light bulb**: This will also produce an electric current, as current flows from the negative terminal to the positive terminal through the circuit.
In summary, **all options (A, B, C, and D) can produce an electric current under certain conditions**. However, options C and D clearly describe direct connections involving a battery that will generate current effectively.
