Name a device that helps to maintain a potential difference across a conductor.
How much energy is given to each coulomb of charge passing through a 6 V battery?
Calculate the quantity of heat produced in a 20 Ω resistor carrying 2.5 A current in 5 minutes.
Define one coulomb charge.
A potential difference of 20 volts is applied across the ends of a resistance of 5 ohms. What current will flow in the resistance?
In the circuit shown below:
The potential difference across the 3 Ω resistor is:
If the potential difference between the ends of a fixed resistor is halved, the electric power will become:
Three resistors are connected to a 12 V battery as shown in the figure given below:
(i) What is the current through the 8 ohm resistor?
(ii) What is the potential difference across the parallel combination of 6 ohm and 12 ohm resistor?
(iii) What is the current through the 6 ohm resistor?
A boy records that 4000 joules of work are required to transfer 10 coulombs of charge between two points of a resistor of 50 Ω. The current passing through it is:
A current of 1 ampere flows in a series circuit containing an electric lamp and a conductor of 5 Ω when connected to a 10 V battery. Calculate the resistance of the electric lamp.
Now if a resistance of 10 Ω is connected in parallel with this series combination, what change (if any) in current flowing through 5 Ω conductor and potential difference across the lamp will take place? Give reason.
