3) To measure the current through a resistor in a circuit with an ammeter, you must A. place the two leads of the meter on the two ends of the resistor. B. place the black lead at the negative end of the battery and the red lead on each end of the resistor. Then subtract the two readings to get the current C. break the circuit at the resistor and hook the meter up to each of the ends of the broken circuit. D. break the circuit at the battery and hook the meter up to each of the ends of the broken circuit
