True

False

2 points   

QUESTION 2

Only conductors can have a net charge on them.

True

False

2 points   

QUESTION 3

Current is defined as the rate of flow of positive charge through a circuit in units of amperes.

True

False

2 points   

QUESTION 4

More resistance added to a circuit (at some constant voltage) will slow down the current in that circuit.

True

False

2 points   

QUESTION 5

In general, the gravity force between electrons and protons in an atom is larger than the electric force.

True

False

Explanation / Answer

1) False

explanation: Resistor will stop the passage of electrons but not take away the electrons

2) False

explanation: Every body have charge on them, but depending on conduction property the bodies are classified as conductors, insulators, and semiconductors.

3) False

explanation: Current is the rate of flow of negative electrons

4) True

explanation: According to Ohm's law, i = V/R ; At constant potential, current is inversely proportional to the resistance

5) True

explanation: If electric force is more betweeen the positive protons and negative electrons they may combine due to opposite charges, but its not happening. So gravity force is more than the electric force
