1. The electrical resistance of an electrical conductor is directly proportional

Question

1. The electrical resistance of an electrical conductor is directly proportional to:
a. The applied electrical field strength
b. The resistivity of the conducting metal
c. The amount of time during which electric current flows through the conductor
d. The cross-sectional area of the conducting material
e. The number of electrons flowing through the conductor each second

2. When two resistors are connected in such a way that all conduction electrons must pass through first one resistor then through a second resistor to complete the circuit the resistors are said to be connected in:
a. By Ohm's Law
b. So they can form a current loop
c. In parallel
d. In series
e. In tandem

3. When a galvanometer is made into a voltmeter we must connect:
a. a high resistance element in series
b. a low resistance element in parallel
c. a high voltage battery in parallel
d. a high voltage battery in series
e. a Kirchoff's rule adaptor across the meter

4. A voltmeter connected directly to the terminals of a batter which is connected to an electric current through which a large current is flowing will indicate:
a. The resistivity of the battery
b. The EMF of the battery
c. The terminal voltage of the battery
d. The amount of current flowing through the circuit
