Reverse direction.
It measures very small currents.
It can handle large currents.
It can detect and indicate ac voltages as well as dc voltages.
It draws a large current from a power supply.
Gets warm when dc flows through it.
Is a thin, straight, special wire.
Generates dc when exposed to visible light.
Generates ac when heated.
The electromagnet meter costs much less.
The electromagnet meter need not be aligned with the earth’s magnetic field.
The permanent-magnet meter has a more sluggish coil.
The electromagnet meter is more rugged.
They increase meter sensitivity.
They make a meter more physically rugged.
They allow for measurement of large currents.
They prevent overheating of the meter movement.
High internal resistance.
Low internal resistance.
The greatest possible sensitivity.
The ability to withstand large currents.
In series with the circuit that works from the supply.
Between the negative pole of the supply and the circuit working from the supply.
Between the positive pole of the supply and the circuit working from the supply.
In parallel with the circuit that works from the supply.
A small voltage between points under test
A slight change in switchable internal resistance
A small change in the resistance to be measured
A slight error in the range switch position
Can measure lower voltages.
Draws less current from the circuit under test.
Can withstand higher voltages safely.
Is sensitive to ac voltage as well as to dc voltage.
