Define one coulomb charge.
If a potential difference of 10 V causes a current of 2 A to flow for 1 minute, how much energy is transferred?
A resistance of 20 ohms has a current of 2 amperes flowing in it. What potential difference is there between its ends?
In the circuit diagram given below, the current flowing across 5 ohm resistor is 1 amp. Find the current flowing through the other two resistors.
In the circuit shown below:
The potential difference across the 3 Ω resistor is:
Calculate the current flowing through each of the resistors A and B in the circuit shown in the following figure.
What would you suggest to a student if while performing an experiment he finds that the pointer/needle of the ammeter and voltmeter do not coincide with the zero marks on the scales when the circuit is open? No extra ammeter/voltmeter is available in the laboratory.
What do you understand by the resistance of a wire?
The figure shows a circuit. When the circuit is switched on, the ammeter reads 0.5 A.
(i) Calculate the value of the unknown resistor R.
(ii) Calculate the charge passing through the 3 Ω resistor in 120 s.
(iii) Calculate the power dissipated in the 3 Ω resistor.
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.
