Chhattisgarh Board Solutions for Chapter: Electric Current and Circuit, Exercise 5: Exercise

What would be the effect if one bulb out of three arranged in parallel combination malfunctions?

Find the equivalent resistance between A and B in the circuit diagram given below.

If a potential difference generated by a battery across a circuit of two bulbs, combined in series, is $6 \mathrm{volts}$, and the potential difference at the first bulb is $2 \mathrm{volts}$, find out the potential difference at the second bulb?

If two conducting wires of same length and cross-section are combined first in series and then in a parallel combination, what would be the ratio between the quantity of heat generated in the two series and parallel circuits?

A  $9 \mathrm{volt}$ battery is arranged in series combination with resistors of $2 \mathrm{\Omega }, 3 \mathrm{\Omega }, 4 \mathrm{\Omega }, 5 \mathrm{\Omega }, 12 \mathrm{\Omega }$, what would be the current flowing through $2 \mathrm{\Omega }$ ?

List the various appliances working on the thermal effect produced by the electric current, which are used in our homes, and discuss their working.

On a bulb, $200 \mathrm{V}-100 \mathrm{W}$ is printed. What would be the resistance of the bulb? If $5$ of these bulbs burn for $4$ hours, what would be the amount of electricity consumed and cost of electricity, if the rate is $50 \mathrm{paise}$ per unit?

How would you combine $3$ resistances of  $2 \mathrm{\Omega }, 3 \mathrm{\Omega }$ and $5 \mathrm{\Omega }$, so that equivalent resistance is $2.5 \mathrm{\Omega }$. Draw the circuit.
