Answer: in series with it.
- A in series with it
- B in parallel with it
- C in both ways at once
- D in neither way
Correct answer: A. in series with it
Explanation: A high resistance in series limits the current so the meter can read voltage across a large range.
The magnetic field around a long straight current-carrying wire forms concentric circles, with direction given by the right-hand rule (point thumb along I, fingers curl in the direction of B).
Concept context
Magnetic force on moving charges and currents, the Biot-Savart law, Ampere's law, and the cyclotron - how electric currents create and respond to magnetic fields.
