The work done per unit positive charge is known as...
Emf
Voltage
Current
Resisitor
For a fixed supply voltage the current flowing though a conductor will decrease when
Cross sectional area of the conductor is increased.
Length of the conductor is increased.
Length of the conductor is reduced.
Cross sectional area is increased and length is decreased.
A circuit contains two unequal resistors in parallel.
Current is same in both.
Large current flows in larger resistor.
Potential difference across each is same.
Smaller resistance has smaller conductance
According to ohms law for a conductor at constant Temperature:
Current in the conductor is inversely proportional to the potential difference across it.
Current is not affected by a decrease or increase in potential difference.
Current in the conductor is directly proportional to the potential difference across it.
All of the above
Which of the following material is not used to make a conductor?
Silver
Copper
Aluminium
Carbon
The main difference between a parallel and a circuit series is .
The current is decreased by a half in parallel circuits and is doubled in series circuits.
The voltage across the parallel circuit is the same across each branch yet in series the voltage is the sum of the voltages across each component.
Voltage is higher in series circuits compared to parallel.
Voltage is used up in series circuits compared to parallel circuits

The picture shows an electrical circuit. This circuit is a series circuit because:
It uses a single battery.
It has 3 light bulbs.
The electrical current is divided between the three light bulbs.
The same current flows through all three light bulbs.
