Applying Magnetic Field

Connecting a resistance in series with a galvanometer, is the way to convert a galvanometer into ______.

• an ammeter

• a voltmeter

The resistance that is connected in series with a galvanometer is called _______.

• multiplier

• shunt

• equivalent

• none of the above

Connecting a multiplier with a galvanometer in series will affect:

• the total current

• the voltage of each resistance

The coil will damage if it is used to detect high voltage, so this voltage has to split over another resistance called a multiplier as a voltage divider

• True

• False

Which is the correct formula for the force on a current-carrying wire in a magnetic field?
